Niles Boulevard Bridge Construction Update
Submitted By City of Fremont
Replacement of the Niles Boulevard BridgeÑconnecting the City of Fremont and Union CityÑcontinues. The new structure, immediately south of the existing bridge, will remain open throughout construction, which is anticipated to be completed in the fall.
Traffic shifts will be required to transition traffic off the old bridge and onto the new one. The first shift occurred the week of July 31 and involved moving eastbound traffic onto the new bridge, while westbound traffic temporarily remained on the old bridge. Once construction between the bridges is completed, all traffic will shift to the new bridge in a temporary alignment so that the old bridge and embankments can be removed. Once this is complete, traffic will be placed in its final alignment.
Weekday and weekend night work to demolish the old bridge is scheduled to begin the week of August 24 and continue through the first week of September. This work is scheduled to take place from 1 a.m. to 10 a.m. Weekend and weekday night work is necessary due to the short time windows available for the construction team to conduct operations over the BART tracks. This work is conducted Monday through Friday 1:45 a.m. to 3 a.m., Saturday 1:45 a.m. to 5 a.m., and Sunday 1:45 a.m. to 7 a.m.
Anticipated work dates and times are subject to change due to weather, unforeseen conditions, or the availability of on-site Union Pacific Railroad flaggers and BART safety monitors.
Changeable message boards near the project site indicate upcoming weekend night work dates and times. Notice of future weekend, night, or noisy activities will be provided as work is scheduled; weekly updates are posted on the project website.
