On June 7, 2011, the City Council awarded a contract to Columbia Electric, Inc. to construct the
Dublin Traffic Signal Improvements project. The project included the installation of a new traffic
signal at the intersection of Amador Valley Boulevard and Brighton Drive. This was the result of
a traffic signal warrant analysis of said intersection which concluded that installation of a traffic
signal was justified. In addition, the project included upgrading of the existing traffic signal at the
intersection of San Ramon Road and Shannon Avenue to improve pedestrian safety for school
children crossing San Ramon Road at Shannon Avenue. The projects are identified on the
location map (Attachment 1).
Staff has determined that the work under this contract is now complete and ready for
acceptance. The new traffic signal installed at the intersection of Amador Valley Boulevard and
Brighton Avenue has significantly reduced the queuing of cars at said intersection particularly
during school drop -off and pick -up periods, and pedestrian safety has been increased with the
installation of signalized crosswalks. Furthermore, the upgraded signal at the intersection of
San Ramon Road and Shannon Avenue has provided safer pedestrian access across Ramon
Road.
