Some Facts About New Hampshire’s Infrastructure:New Hampshire has approximately 17,000 miles of state and town roads, turnpikes and interstate highways. There are 3,795 bridges in the state. As of 2010, the New Hampshire Department of Transportation plowed more than 800 lane miles of roads and put down 180,000 tons of salt for snow and ice control annually.The state was given a “C” grade by the American Society of Civil Engineers for the condition of its roads and bridges. New Hampshire was rated among the worst in the country for the poor condition of its bridges by Transportation For America. On average, bridges are older in New Hampshire than those in the rest of the country. There are hundreds of bridges on the so-called “red list,” which means that the bridges have major structural problems and need to be repaired or replaced.The state also has a poor record when it comes to public transportation. New Hampshire has no comprehensive rail system and is rated 42nd in terms of investment in public transportation according to the State Department of Transportation.The majority of New Hampshire’s infrastructure funding comes from vehicle registration fees and gas taxes. The state takes out fewer bond loans than other states and considers its funding a “pay as you go” system. The gas tax, the lowest in New England, has not been raised since 1991. The 2011 Legislature did away with a motor vehicle fee increase. That change has meant more $30 million a year in cuts to DOT.The $800 million expansion of I-93 from Salem to Manchester began in 2006, but has been delayed several times because of a lack of funding. Supporters of the expansion say it will update one of the country’s most congested highways and bring needed tourism revenue to the more isolated and less economically robust northern part of the state. Traffic on I-93 has increased 600 percent since the highway was built in the 1960s and approximately 80,000 cars now drive on it each day.Summary provided by StateImpact NH

N.H. DOT Suspends Installation Of Potentially Faulty Guardrail Component

New Hampshire’s Department of Transportation has suspended the installation of a potentially faulty guardrail end unit, but officials say they’re waiting for more information before removing the 1,300 units already installed.

Department of Transportation spokesman Bill Boynton says the state has been installing the Trinity ET-Plus pieces for nearly a decade.

“These are devices that are meant to absorb energy and basically give and have the guard rail attached it to collapse and veer away from it if the end unit is hit.”

Earlier this week a Texas jury ordered the manufacturer of the units to pay $175 million in damages. A whistleblower brought the suit, claiming the products were unsafe after a design change in 2005.

The units had been granted federal safety approval before the design was changed and have been installed in all 50 states.

Boynton says there’s approximately 1,300 of these units installed across New Hampshire roads, but says the department is waiting for more information before trying to track those down.

“We haven’t decided yet about moving forward in terms of any kind of removal. We’re not convinced they aren’t safe in terms of what they were designed to do.”

Boynton says there are questions about whether the guard rail end unit led to more serious injuries in a June accident on I-93 in Ashland.
