Contra Costa County Public Works said it will begin rehabilitation work on the Robert I. Schroder Pedestrian Bridge on Monday, October 5, 2026; the county set an anticipated completion date of Thursday, December 31, 2026, barring unforeseen circumstances.
Work will occur at night; hours are 9:00 p.m. to 5:00 a.m., Sunday through Thursday, excluding holidays, weather permitting, the county said. Drivers can expect 10-minute delays on Treat Boulevard during construction and occasional lane closures, the county said.
The county said the Bridge will be closed for the duration of the project. Pedestrian and bicycle users on the Iron Horse Trail will be redirected to the existing street crossing on Treat Boulevard for approximately 3–4 months while repairs proceed; detour signs will guide users, the county said.
Planned work items listed by the county include replacing the bearing pads, paint repairs, a bridge deck treatment, and sidewalk and curb replacement. Funding is provided by Measure X Funds and Park Dedication Funds, the county said.
The county said approximately four night-time road closures will be needed to accommodate the bearing pad replacement. During those closures the county said it will implement an approximate 5-mile traffic detour; the county has not yet posted the dates for those planned closures and said the dates will be provided on the project website.
What the county did not specify: exact dates for the four night-time closures, the contractor on the job, and any impacts to transit routes or emergency-service response times. The schedule is subject to change for weather or other unforeseen issues, the county said.
Practical steps for travelers: expect a full closure of the bridge through December 31; plan for 10-minute nighttime delays and occasional lane closures on Treat Boulevard; follow detour signs and use the Treat Boulevard street crossing if you walk or bike.
