FROM: J. MICHAEL WALFORD, PUBLIC WORKS DIRECTOR Costa
DATE: OCTOBER 30, 1984 County
SUBJECT: REPORT ON THE WEEKtND-HOLIDAY TRAFFIC CONGESTION ON INTERSTATE 680 APPROACHING THE
BENICIA-MARTINEZ BRIDGE "
Specific Requests or Recommendation(s) Background & Justification
RECOMMENDATION
Refer the item to the Contra Costa Transportation Advisory Committee (CCTAC) to coordinate
efforts that will provide additional capacity on the Benicia- Martinez Bridge.
BACKGROUND
On August 28, 1984 the Board directed the Public Works Department to investigate with
Caltrans the weekend holiday northbound traffic congestion on I-680 approaching the Benicia-
Martinez Bridge.
As part of the Department's investigation aerial photographs were taken on Friday, August 31,
1984 during the evening commute period. The photographs did not indicate the magnitude
of the problem that we had envisioned. The 1984 State Transportation Improvement Program
(STIP) includes a project on the Benicia-Martinez Bridge. Part of that project will be to
restripe I-680 from Marina Vista to the toll plaza for three lanes, and the construction of
two additional toll booths. This project is scheduled to start construction in Fall
of 1985.
Caltrans has recently released drafts of their route concept reports for I-680. The
development concept for I-680 at the bridge is an eight-lane freeway. This would necessitate
a new four-lane parallel span. However this project has not been programmed on the STIP.
Caltrans Highway Operations Division is preparing a study on long term solutions for the
Benicia-Martinez Bridge congestion problem. The results of this Study will more than
likely support the need for a parallel bridge.
Based on the above, it is recommended that the Board of Supervisors refer this item to
CCTAC to coordinate efforts on programming a new bridge into the STIP and work with Caltrans
on providing interim measures to alleviate congestion on the northbound approaches to the
Martinez-Benicia Bridge.
