The average age of these sub-par bridges is 55 years — over the typical design life of 50 years and 14 years older than the average age of all Oregon bridges (41 years old). More than one in twelve Oregon bridges were built before 1948 — which means more than 680 bridges are older than the Korean War and creation of Medicare.

With great energy and enthusiasm, they enacted a unique plan that made the Manette Bridge on the day it was christened, truly, the bridge of the people.

The average age of these sub-par bridges is 66 years — well over the typical design life of 50 years and nearly double the average age of all Minnesota bridges (35 years old). More than one in ten Minnesota bridges were built before 1948 — which means more than 1,300 bridges are older than the Korean War and creation of Medicare…Minnesota drivers collectively took close to 628 million trips over deficient bridges in 2014. That’s more than 1.7 million trips per day or almost 1,200 trips every minute taken over deficient Minnesota bridges in 2014.
TRIP
Washington’s residents and businesses require a high level of personal and commercial mobility. Population increases and economic growth in the state have resulted in an increase in the demand for mobility as well as an increase in vehicle miles of travel (VMT). To foster quality of life and spur economic growth in Washington, it will be critical that the state provide a safe and modern transportation system that can accommodate future growth in population, tourism, recreation and vehicle travel.
Watch UDOT crews completely demolish the bridge over I-15 at 400 North in 45 seconds. The freeway was shut down in both directions overnight on the South Davis Improvements Project to complete the work.

The life cycle of New York’s roads is greatly affected by the state and local government’s ability to perform timely maintenance and upgrades to ensure that road and highway surfaces last as long as possible…More than a third – 37 percent – of New York’s major locally and state-maintained urban roads and highways have pavements in poor condition. An additional 43 percent of the state’s major urban roads have pavements in mediocre or fair condition, and the remaining 20 percent are in good condition.
It’s hard to believe, but it’s been almost 10 years since anyone drove from Mount Pleasant to Charleston on the Grace Memorial Bridge. To commemorate the occasion, For this week’s throwback Thursday, SCDOT video producer Drew Stewart dug up some video of the bridge that is now, “gone with the wind.”
