AEM Commends Administration for Surface Transportation Bill Proposal, As U.S. Badly Needs Multi-year Legislation

AEMCorpLogoThe Association of Equipment Manufacturers (AEM) is glad to see the Obama Administration proposing reauthorization for a multi-year surface transportation bill and engaging in the vitally important conversation about the future of America’s serious need for greatly improved infrastructure.

Rick Patek, AEM Chair and Group President, Aggregate and Mining, Astec Industries Inc., made this statement:
 
“Overall, we are glad to see today’s proposal, and are particularly pleased to see that the Administration has included a funding plan for this multi-year reauthorization.  It’s moving in a good direction, but our concern, as with all such proposals, is that it does not provide the desperately needed, long-term stable financing solution the country demands.  It would, however, expand broadband capacity and streamline project delivery, both of which are critical.

“To plan and make appropriate capital investments in the modernized transportation system that’s needed to maintain America’s leadership in the global economy, we must have a financing plan that takes us far into the future, much beyond a four-year period. Congress needs to act before the Highway Trust Fund is unable to meet its obligations. We encourage everyone – House, Senate, Administration – to keep this process moving forward and work hard together to craft the long-term solution we must have.”

AED Statement on White House Draft Surface Transportation Bill

Associated Equipment Distributors (AED) President and CEO Brian P. McGuire released the following statement regarding the Obama administration’s draft reauthorization proposal for highways and surface transit, which was delivered to Congress by Secretary of Transportation Anthony Foxx on April 29, 2014.

“We’re pleased to see President Obama and Secretary Foxx playing an aggressive leadership role on road, bridge, and transit issues. With the federal highway program on the verge of collapse, we need innovative thinking about to how build, fund and finance America’s 21st century transportation system. We may have differences with the administration about some priorities and program specifics, but we’re on the same page about the need to make infrastructure a priority. We hope the administration’s comprehensive proposal is a catalyst for quick action by Congress to ensure the highway program’s near-term solvency and long-term stability. AED members look forward to working with the administration and lawmakers in both parties to achieving that goal.”

ARTBA Reports:As Collapse of Federal Support for Highway & Bridge Investment Draws Near, More than 63,000 U.S. Bridges Need Structural Repair, New Analysis Find

image001Data from a new government report show that if all the structurally deficient bridges in the United States were placed end-to-end, it would take you 25 hours driving 60 miles per hour to cross them.  That’s like driving the 1,500 miles between Boston and Miami.  And it’s a problem that’s close to home.

An analysis of the 2013 National Bridge Inventory database recently released by the U.S. Department of Transportation (USDOT) shows cars, trucks and school buses cross the nation’s more than 63,000 structurally compromised bridges 250 million times every day.  The most heavily traveled are on the Interstate system.

The problem could get a lot worse, the chief economist for the American Road & Transportation Builders Association (ARTBA) says, as states across the nation face a slowdown in reimbursements for already approved federal-aid highway projects in August.  Without congressional action, Dr. Alison Premo Black says there will be no Highway Trust Fund support for any new road, bridge, or public transportation projects in any state during FY 2015, which begins October 1.

“Letting the Highway Trust Fund investment dry up would have a devastating impact on bridge repairs,” Black says, noting the trust fund has supported $89 billion in bridge construction work by the states over the past 10 years.  “It would set back bridge improvements in every state for the next decade.”

“The bridge problem sits squarely on the backs of our elected officials,” Black says.  “The state transportation departments can’t just wave a magic wand and make the problem go away.  It takes committed investment by our legislators.  Members of Congress need to come to grips with that.  Some of our most heavily travelled bridges were built in the 1930s.  Most are more than 40 years old.”

Bridge decks and support structures are regularly inspected by the state transportation departments for deterioration and are rated on a scale of zero to nine—nine being “excellent” condition.  A bridge is classified as structurally deficient and in need of repair if its overall rating is four or below.

While these bridges may not be imminently unsafe, ARTBA suggests they be sign posted so the public knows they have structural deficiencies that need repair.

The ARTBA analysis of the bridge data supplied by the states to the USDOT found:

  • The 250 most heavily crossed structurally deficient bridges are on urban interstate highways, particularly in California.  With one exception, all are at least 39 years old.
  • Pennsylvania (5,218), Iowa (5,043), Oklahoma (4,227), Missouri (3,357) and California (2,769) have the highest number of structurally deficient bridges; Nevada (36), Delaware (56), Utah (117), Alaska (133) and Hawaii (144), the least.
  • At least 20 percent of the bridges in four states—Pennsylvania (23 percent), Rhode Island (22 percent), Iowa (21 percent) and South Dakota (21 percent)—fall in the structurally deficient category.

State specific bridge information from the analysis—including rankings and location lists of the 250 most heavily travelled structurally deficient bridges in the nation and 10 most heavily travelled in each state—is available in the “Economics” section of www.artba.org.

The Socio-economic Importance of Road Construction

By Krysten Jetson

Excellent infrastructure is the backbone and chief driver of socio-economic development, which every country strives to achieve. In the US during the 1950s and 1960s, massive and strategic investment was made to build world-class interstate highway systems and transportation infrastructure. All this contributed in making our country the undisputed world leader and an economic superpower. Investment in surface transportation helps to connect people, drive commerce and maintain global competitiveness. At the aggregate level, efficient transport systems reduce costs in many economic sectors by providing better accessibility to markets, increasing employment, bringing in foreign investment and improving global presence of countries. Transport carries an important social, economic and environmental load, which can never be over-stated.

The socio-economic significance of infrastructure development is extensive. Let’s have a look into the impact of infrastructure development on our lives.

Economic effects of transportation infrastructure

In the US, the Federal Highway Administration estimates that $170 billion in capital investment would be needed on an annual basis to significantly improve conditions and performance of our infrastructure. Once the envy of the world, America’s critical infrastructure, including its roads, bridges, mass transit systems and systems for delivering energy, may soon find it difficult to meet society’s needs. Let’s see how the transport infrastructure affects the economy.

1)    Mobility and economic effects. Economies that possess greater mobility are often those with better opportunities to develop, than those with scarce mobility. Reduced mobility impedes development while greater mobility is a catalyst for development. According to recent reports, forty-two percent of America’s major urban highways remain congested, costing the economy an estimated $101 billion in wasted time and fuel annually. Better roads and connectivity can translate into massive savings, both for the state as well as citizens. Transportation also weaves a complex web of relationships between consumer, manufacturer and distributor. The productivity of space, capital and labor is enhanced with the efficiency of distribution and personal mobility.

  • Less cost. A more efficient distribution and procurement network directly results in lesser prices for consumers. This is because transportation costs form a major chunk of the total cost of each output in manufacturing.
  • Wider reach to business. With better transport facilities there is access to a wider market or consumer base which leads to better economies of scale in production, distribution and consumption.
  • Better and diverse products. Good infrastructures give access to larger and diverse base of quality inputs, and broader markets for diverse outputs. This is good for the consumer as well as the manufacturer.
  • Increased competition. When transportation is efficient, there is a wider market for goods and services, resulting in increased competition. A wider array of goods and services to choose from, reduced cost and improved quality are some of the benefits passed on to the consumers. Also, this promotes innovation and technological advancement.

2)    Mobility and economic opportunities. Transportation development and improvement that took place since industrial revolution has shaped and transformed economies and social geography of nations.

  • Attractive to foreign investors. Excellent infrastructure has always made the US an attractive destination for global corporations to invest and do business in. Good connectivity lowers transport costs, and contributes to reliable and cost-efficient supply chain management. A poor transport service level can negatively affect the competitiveness of regions and corporations, and thus have a negative impact on the brand value of our country.
  • Attractive to new-age businesses. Transport infrastructure is always important, but their relative importance in supporting the changing demands of economy  may evolve. When an economy shifts from being manufacturing-based to service-based, there is more orientation towards efficiency of logistics and urban transportation. An infrastructure that grows and evolves to support the changing needs of the economy is attractive to both businesses as well as stakeholders like new-age employees and students.
  • Increased employment opportunities. A growing economy opens up new and expanding range of employment potential as well. New businesses and sunrise industries are voracious creators of job opportunities. The ‘feel good’ vibe that they bring into ageing, developed economies can be quite rejuvenating and energizing. Transport systems need to evolve in time and space as they include the timing and the nature of the impact of transport on economic development.

Social effects of transportation infrastructure

Roads and bridges change the face of landscapes. Increased connectivity brings societies closer to the outside world, and brings in influences from far and wide. The societal and cultural impacts are many.

  • Mobility benefits. Though societies on the whole reap benefits of growing and improved connectivity, some people enjoy it more than the others. Higher the income, the more the opportunity to benefit from infrastructure growth and economic opportunities. They also have increased ability to afford travel. Inclusive growth, by promoting connectivity in rural, under-developed and poorer regions can help all sections of society benefit.
  • Rising land value. With roads and highways linking vast areas of land with cities and towns, land prices also show a trickle-down effect from those in urban locations. There has been quite marked and sharp increase in land prices observed once infrastructure improves.
  • Improved quality of life. When transportation facilities increase, especially in far-flung and land-locked areas, prices of goods and services come down drastically. A wider array of products is available at reasonable prices. This helps to improve household finance and savings.
  • Congestion and accidents. A growing population and ageing infrastructure leads to overcrowding and congestion in urban areas. Serpentine traffic-jams lead to wastage of time, fuel and energy. Accidents also become common. Environmental pollution used to be a major issue, but with strict emission laws there is a continued effort to curb the menace.

Conclusion

Infrastructure determines the longevity and success of a nation. A good, upgraded and efficient transport infrastructure is essential for a strong and thriving economy. According to the American Society of Civil Engineers, an investment of $3.6 trillion will be needed by 2020 for the repair, upgrade and development of infrastructure. But the available funds are nowhere near this gigantic figure. Experts say that while it is important to have more money because the needs are so great, there is also a need to cut spending on shiny new projects in places with insufficient demand. The authorities need to spend on maintaining and improving infrastructure in the places with some of the greatest need.

All Jammed Up

lookingDSfromBridgeIce Jams in Powder River at Arvada, WY, downstream of the bridge.

April showers may bring May flowers, but spring can also bring ice jams to the thawing rivers and streams across the northern United States.

An ice jam or ice dam, is a buildup of broken ice in the river system. It can be a problem that causes the water to back up over the top of highway bridges, roads, or into cities. At times, they can cause flooding. Ice jams can be large–backing up water for miles, or small and only back up water in a small area locally.

An ice jam can damage bridges with the amount of water pushing on the jam from behind; it can force the ice to push the bridge – moving it slightly.

USGS monitors ice jams across the north using cameras as well as by collecting ice thickness information when technicians do regular streamgage work or when measuring discharge on the rivers in the spring.

For example, each year, the Maine Emergency Management Agency and U.S. Coast Guard asks the USGS to measure the ice thickness and provide an ice jam flood potential on the Kennebec River. The U.S. Coast Guard has used their ice breakers to clear the ice in the lower Kennebec River in years when the ice jam flood potential was high.

Greg Stewart, data section chief for the USGS New England Water Science Center, said its part of the agency’s job to monitor river flows throughout the state of Maine and to measure the stream flow underneath the ice.

USGS technicians take ice cores to measure ice thickness at various places on the rivers. In order to make an ice measurement, it’s necessary to drill between 25-30 holes in the ice. Then, thickness is recorded at just several of the holes to help document the measurement conditions.

That information allows the USGS to assess the risk of ice jams, flooding or other problems when the ice begins to melt, Stewart said. According to Stewart, when ice jam flooding starts to happen, there is very little time and very little warning.

Thickness of the ice and how fast a melt occurs affects the ice jam flooding potential. For example while the weather is cold, and the water is freezing you have ice accumulation. When the weather changes and it starts to warm the ice begins to melt and begins to break up. A quick warmup with the ice strong and still in place can cause significant ice jam flooding.

Another sign of spring is the melting snowpack, which is the result of accumulated layers of snow with generally more at high altitudes. Snowpacks feed rivers and streams providing an aquatic life habitat, hydro power, a possible source of drinking water, but they are also a potential flood hazard.

With a quick warm up of high temperatures over a short period of time, there is an increased likelihood of flooding from snowpack melt, but when you have a gradual increase in spring temperatures with moderate temperatures during the day and slightly below freezing at night the flooding potential is decreased slowly and safely.

According to Stewart, when the snowpack starts to melt, historically in March, that’s when snowmelt driven runoff begins and the USGS looks at the flooding potential.
