Ribbon cutting for I-580/Castro Valley Interchange improvements

Submitted By Tess Lengyel

The newly-formed Alameda County Transportation Commission (Alameda CTC) celebrated completion of a major interchange project that improves traffic on I-580 at Redwood Road and on nearby streets, including access to the Castro Valley Business District and BART station with a ribbon-cutting ceremony on the I-580 westbound off-ramp of Redwood Road in Castro Valley at 1 p.m. on Monday, September 20, 2010.

Congresswoman Barbara Lee, Assembly Member Mary Hayashi and Assemblyman Alberto Torrico's representatives joined Senator Ellen Corbett, Supervisors Nate Miley, Scott Haggerty and Union City Mayor Mark Green, Chair of the Alameda CTC, in the ribbon-cutting ceremony.

In June 2008, the Alameda County Transportation Improvement Authority (ACTIA) awarded construction of the interchange to RGW Construction. The project involved improving access to and from I-580 in Castro Valley. Improvements included creating a full interchange at Redwood Road (i.e. adding a new eastbound on--ramp and a westbound off--ramp), constructing a new eastbound off--ramp from I-580 to Grove Way and removing two existing ramps: the eastbound off--ramp to Center Street and the westbound on--ramp from Castro Valley Boulevard. The new ramps will reduce traffic congestion, while providing better mobility for the local area.

The I-580 Castro Valley Interchange Improvement Project is part of the voter-approved improvements implemented in Central Alameda County. Measure B, Alameda County's half-cent transportation sales tax, provided almost 80 percent of the overall funding for the I-580 Castro Valley Interchange Improvement Project. Other funds include more than $4.8M of the State Transportation Improvement Plan (STIP), which is derived from Proposition 1B infrastructure bonds, approved by voters in November 2006 and $1.9M in federal funds.

"This project is one more example of how we are delivering the promises of transportation investments to voters who entrusted us with Alameda County's half-cent transportation sales tax measure. Measure B funds critical infrastructure, operations and maintenance of our transportation system," noted Art Dao, the newly-appointed Alameda CTC Executive Director.

I-580 Interchange improvements include a new westbound off-ramp from I-580 to Redwood Road; a new eastbound on-ramp from Redwood Road to I-580; a new eastbound off-ramp from I-580 to Grove Way; removal of an existing eastbound I-580 off-ramp to Center Street; and removal of an existing westbound on-ramp from Castro Valley Boulevard to I-580.
