Freeway closures planned this weekend at new BART station

Crews to install pedestrian walkways across I-580

by Jeb Bing

After being delayed more than a year by engineering problems, contractors are back at the new West Dublin/Pleasanton BART station to connect the aerial pathways that will link the station to Dublin and Pleasanton.

Starting at 11 p.m. Saturday, two lanes of westbound I-580 will be closed as construction crews prepare the walkways on the Dublin side of the freeway. All westbound lanes will actually be shut down completely from 2 a.m. to 6 a.m. while the work is under way. All lanes are expected to reopen by 9 a.m. Sunday.

Traffic will be detoured from the Dougherty Road off-ramp to Dublin Boulevard where motorists can continue traveling west to San Ramon Road, where they can re-enter the freeway.

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

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

The station is now expected to open late this year or early in 2011.

Installation of the pedestrian walkway on the Pleasanton side will take place over two weekends with eastbound lanes affected July 10-11 and again July 17-18.

Allyn Amsk, public information officer for Caltrans, said partial closures of the freeway's eastbound lanes will begin at 11 p.m. on both Saturdays with full closures from 2 a.m. to 6 a.m. both Sundays. Eastbound motorists will face detours at Foothill Road, where they will be directed to Stoneridge Drive to the northbound I-680 ramp and then back onto I-580.
