Total closures of Dublin Boulevard between Dougherty Road and Hacienda Drive are scheduled to take place during two weekends this month for the installation of a new Iron Horse Regional Trail overcrossing.

The ongoing project to build a bridge for pedestrians and cyclists over busy Dublin Boulevard through the area will require a closure this Saturday (Sept. 9) at 11 p.m. through Sunday (Sept. 10) at 11 p.m. to install the overcrossing. The second closure, to pour the concrete walkway on the bridge, will follow Sept. 23 at 11 p.m. through Sept. 24 at 7 a.m.

Detour signs will be on display to direct drivers south to Pleasanton, according to Dublin city officials.

City staff have said the goal of the project is to allow for safer and quicker crossing of pedestrians and cyclists along the Iron Horse Trail.

Currently, pedestrians must take additional steps and directions to continue on the route. The bridge will now allow pedestrians to stay on the trail and cross over multiple lanes of vehicle traffic.

"The existing trail at-grade crossing of Dublin Boulevard is quite skewed," city officials said in the traffic advisory. "Trail users approaching Dublin Boulevard from the southeast are currently required to turn left and use the sidewalk along the south side of Dublin Boulevard for approximately 200 feet, cross the street at the existing Scarlett Drive signalized intersection, and then turn right and use the sidewalk along the northside of Dublin Boulevard for approximately 100 feet to get back to the Trail."

According to the city, local vehicle and pedestrian access will be allowed up to Scarlet Drive and Sterling Street during the Dublin Boulevard work. The city has advised that exact dates and times of the closures may vary depending on unpredictable circumstances.

The overcrossing will span an estimated 230 feet over Dublin Boulevard with a height of 20 feet at its tallest.

The project is estimated to cost $14 million, funded by Alameda County Measure BB, BART Measure RR and the Bay Area Air Quality Management District Transportation Fund for Clean Air. Prior to initiating construction, the city completed several studies on the feasibility and impact of such an overcrossing installation.

Contracted by the city of Dublin, Goodfellow Bros. Sequoia A JV, began construction of the project in April 2022 with foundation piles, concrete bents and elevated walkways. Now the final step involves lifting and placing the pre-built pieces into place.
