The Congestion of Good Intentions in L.A.

The addition of a 10-mile carpool lane to one of Los Angeles' busiest freeways is creating a huge stress on the region's transportation system.

Despite the project's intention to improve transportation in the congested L.A. area, the project is expected to tangle the roads and the commutes of millions for years.

"The goal would appear simple and even admirable: to add a 10-mile car-pool lane on the 405, among the most reviled and traffic-snarled freeways in Los Angeles, as it approaches and rolls north over the Sepulveda Pass, connecting the city's west side to the San Fernando Valley. But given the nature of this particular operation - basically open-heart surgery on the central circulatory system of this traffic-obsessed town - it is anything but.

What looms is an alleged three-year marathon of open and closed exit ramps, shut and narrowed lanes, banging overnight construction, detours sending traffic rumbling through some of the city's most elegant neighborhoods, and a reminder of the price paid for the absence of meaningful public transit. It is all being chronicled in a stream of e-mail alerts and Twitter postings from transportation officials, who are doing what they can to keep everyone calm - with mixed success."
