AMERICAN SOCIETY OF CIVIL ENGINEERS

Since the last update of the American Society of Civil Engineer (ASCE)’s Bay Area Infrastructure Report Card in 2005, we have seen several major infrastructure failures: the gas line explosion in San Bruno, California with major loss of life in 2010; wastewater discharges from Marin County into the San Francisco Bay; and a collapse of the Interstate Route 35 Mississippi River Bridge in Minneapolis, Minnesota with significant loss of life in 2007. All of these are classic examples of aging infrastructure allowed to perform without sufficiently funded monitoring, rehabilitation, and replacement programs.

Bicycle and Pedestrian Fatalities and Population Density

LOS ANGELES COUNTY BICYCLE COALITION
There are many high-density urban areas in Los Angeles County with large numbers of transit -dependent residents and high rates of walking and bicycle usage, yet they tend to contain much fewer, if any, bicycle facilities.

Dear Friends,

 

It is encouraging to finally see clear signs of federal action to support a comprehensive US infrastructure investment plan.

 

Now more than ever, our advocacy is needed to keep stakeholders informed and connected, and to hold politicians to their promises to finally fix our nation’s ailing infrastructure.

 

We have already engaged nearly 280,000 users, and hoping to add many more as interest continues to grow.

 

We require your support in order to rise to this occasion, to make the most of this opportunity. Please consider making a tax-deductible donation to InfrastructureUSA.org.
