Dublin Boulevard Widening Project

Dublin Boulevard Widening Project Before Construction Dublin Boulevard Widening Project After Construction








This two-phased infrastructure project focused on both utility and transportation improvements along Dublin Boulevard.

The first phase involved moving a sewer lift station operated by the Dublin San Ramon Services District, along with moving overhead utility lines underground. Completion of phase one concluded in June 2018.

Phase was finished in April 2020, wherein crews widened the roadway to accommodate a third vehicle lane in the westbound direction as well as bike lanes on both sides of the road. The project also created the following improvements:

  • New sidewalks and ADA-compliant curb ramps
  • A pedestrian bridge over the drainage channel east of Dublin Sports Grounds
  • Resurfacing of the Dublin Sports Grounds parking lot
  • Modifications to median islands
  • Traffic signal system upgrades
  • Converting the previous potable water irrigation system to a new, more sustainable recycled water system
  • A landscaped bioretention treatment area

Phase two was completed in April 2020. Funding for the Dublin Boulevard Widening Project was provided in part by a $3 million Measure BB grant from the Alameda County Transportation Commission.

Dougherty Road Improvements Project

In January 2019, the City of Dublin completed the Dougherty Road Improvements Project, a highly anticipated infrastructure expansion that had been in the works since the City’s 1985 General Plan adoption. The corridor is one of Dublin’s most highly utilized roads, accommodating more than 32,000 vehicle trips per day.

The project provided for the widening of Dougherty Road from four lanes to six between Sierra Lane and the northern City limits, along with corresponding traffic signal modifications. Corridor improvements also included the following:

  • Installation of new Class II bike lanes
  • 1.4 miles of bike/pedestrian pathway improvements
  • Landscaped median islands
  • Storm drainage improvements
  • New curbs, gutters, sidewalks and curb ramps
  • Three new illuminated bus stops
  • Bioretention areas and landscaping along the easterly side of the roadway
  • A complete asphalt overlay with new pavement markings between Dublin Boulevard and the northern City limit
  • An expansion of the City’s fiber optic network to the five intersections to facilitate implementation of an adaptive traffic signal timing system, reducing travel times on Dougherty Road

These improvements to Dougherty Road have reduced roadway congestion and improved BART station accessibility for pedestrians and cyclists. The project was made possible in large part by Measure B and Measure BB grants totaling nearly $17.5 million from the Alameda County Transportation Commission.

Tassajara Road/Camino Tassajara Culvert Replacement Project

An extended road closure was necessary to replace a failing culvert which runs under Tassajara Road. The aging nine-foot diameter culvert was replaced with an 18-foot diameter culvert, that is over 400 feet long. The increased size allows a more stable flow of water, stopped the  deterioration underneath the roadway, and lessens the possibility of emergency road closures in the future. The widening of the road  provides greater safety for motorists traveling along that section of Tassajara Road linking Contra Costa and Alameda Counties.

San Ramon Road Arterial Management Project

The project implemented Traffic Signal Coordination/Transit Signal Prioritization (TSP) related improvements along San Ramon Road from Dublin Boulevard to Vomac Road. This included signal coordination for five traffic signals, updated five traffic signal controllers for current and future TSP , and implemented TSP for three intersection along the corridor. This project also created a buffered bicycle lane along both directions of San Ramon Road. In addition, radar-based bicycle detection devices were installed at the intersection of San Ramon Road and Amador Valley Boulevard.
