The cost of traffic congestion: 7 out of every 10 construction projects delayed

The Associated General Contractors of America recently surveyed 1,200 construction firms across the United States on the impact of traffic congestion.

Not surprisingly, traffic congestion does possess a negative financial impact on construction companies. In Washington, 72 percent of construction projects are delayed at least one day because of traffic.

Here is a sample of questions comparing results in Washington to the national average:
