Westbound I-580 lanes open as walkway installed to new BART station from Dublin side

Pleasanton side next in mid-July as station readies for opening at year's end

All westbound lanes on I-580 alongside the new West Dublin/Pleasanton BART station near Foothill/San Ramon roads are expected to re-open by 9 a.m. after crews installed the first of two pedestrian walkways to the station, which is located in the middle of the freeway.

The work marks the final phase of the station's construction, with BART and Caltrans expected to approve the construction and to open the station to riders at the end of the year or in early 2011.

Overnight, traffic was detoured from the Dougherty Road off-ramp to Dublin Boulevard where motorists could continue traveling west to San Ramon Road and then re-enter the freeway.

Although the steel pedestrian pathways were manufactured and ready two years ago, a year ago, Caltrans, which has oversight for the project, determined that the welds didn't meet the proper safety requirements and could not be repaired. The state transportation agency's standards were different than BART's, which provided the contract specifications.

A BART spokesperson said at the time that it didn't appear the weldings were unsafe, but the agency differed to Caltrans requirement that they be rebuilt, with an additional $2.5 million added to the total cost due to welding problems.

Installation of the pedestrian walkway on the Pleasanton side will take place over two weekends--July 10-11 and again on July 17-18--with eastbound lanes affected at Foothill Road, where they will be directed to Stoneridge Drive to the northbound I-680 ramp and then back onto I-580, according to Allyn Amsk, public information officer for Caltrans.
