BOTTLENECKS ON U.S. HIGHWAYS 

American Highway Users Alliance releases list of worst bottlenecks

(Washington-AP) Feb. 19, 2004 - The number of major traffic bottlenecks is going up. A study by the American Highway Users Alliance finds there are now at least 233 places in the US defined as major bottlenecks, locations where roads simply can't handle the load.

The alliance says there was a 40 percent increase in such spots over the five-year period ending in 2002.

A major bottleneck is defined as a location that caused drivers at least 700,000 hours of delay every year.

The worst headaches are in Los Angeles, which has four of the ten most congested interchanges in the nation. The Mount Doom of traffic is where the Ventura Freeway meets Interstate 405. That's just a few miles from the number-five bottleneck, the I-10-San Diego Freeway interchange.

Numbers two through four are in Houston, Chicago and Phoenix. The highway group says projects like Boston's Big Dig and Albuquerque's Big I are worth the cost, slashing hours of delay by up to 95 percent.

Here is a list of the 24 worst highway bottlenecks, followed by the number of vehicles handled daily and annual hours of delay, according to a study by American Highway Users Alliance.
