Our "structurally deficient" Infrastructure, Much More then Bridges and Roads

And those that need them the most, the economic growth, the business community and the corporations of, do the most damage to and in these modern times pay less and less into maintaining, investing in new and innovative advances to the existing. That cost is more and more the burden of the masses, who also need and use the wide variety of who labor for those businesses and corporations at lower or stagnated compensation for same. Public, many times once combined with private, investments bring much bigger returns and for longer periods of time in revenue initially invested to build or maintain properly. Take down any part of any infrastructure and the cost to rebuild is a total loss, and much much more to rebuild then maintain, in economic revenue needed for private and public treasuries and wasted capital never to be regained.

Millions of Americans will cross 'structurally deficient' bridges this weekend
25 May 2013 - The Washington state bridge collapse that spilled two cars into the Skagit River could give Americans pause as they hit the roads for Memorial Day holiday travel.

With good reason.

This weekend, millions will cross 66,000 bridges that the federal government has deemed "structurally deficient," meaning key elements are in poor condition.

The Federal Highway Administration hastens to note that label doesn't mean they are unsafe or in danger of collapse, but transportation advocates say it highlights a growing crisis of aging infrastructure, deferred maintenance and rebuilding, and design flaws. read more>>>

I-5 bridge collapses north of Seattle

May 24, 2013 - A section of the Interstate-5 bridge near Seattle collapsed after a truck hit an overhead beam, plunging cars into the Skagit River below. Henry Rosoff of CBS affiliate KIRO-TV reports.

The longer the maintenance is pushed 'down the road' the more minor deficiencies, from age and use, grow to more then minor and the engineering becomes more hazardous and dangerous, damaging one or a couple of support beams are engineered and built not to spread in well maintained structures. Accidents that take place before that might just damage sections, and those sections not upgraded properly, now ripple out to cause much more damage and in cases like a bridge causes whole sections to collapse. Over time the minor grow to major deficiencies or minor combine to fail all at one time.

State report: I-5 bridge had gouges, impact damage
25 May 2013 - Officials in Washington state performed a special inspection six months ago on the Interstate 5 bridge that collapsed because there were indications it had been struck by a different vehicle.

An inspection report released Friday by the state Department of Transportation says inspectors brought in a bucket truck to examine the structure and identified tears, deformations and gouges on the northbound side of the bridge. read more>>>

Bridge collapse in Washington state blamed on tractor-trailer

2013 ReportCard on America's Infrastructure | Bridges
Over two hundred million trips are taken daily across deficient bridges in the nation’s 102 largest metropolitan regions. In total, one in nine of the nation’s bridges are rated as structurally deficient, while the average age of the nation’s 607,380 bridges is currently 42 years. The Federal Highway Administration (FHWA) estimates that to eliminate the nation’s bridge deficient backlog by 2028, we would need to invest $20.5 billion annually, while only $12.8 billion is being spent currently. The challenge for federal, state, and local governments is to increase bridge investments by $8 billion annually to address the identified $76 billion in needs for deficient bridges across the United States. read more and launch the report>>>
