Coliseum Station Seismic Retrofit Work to Create Detours


Coliseum Station Seismic Retrofit Work to Create Detours

As part of the BART systemwide Earthquake Safety Program, BART crews will be working inside the COLISEUM Station for seismic retrofit construction.  This work will require construction activity at various locations and stages inside and outside the patron area.  Work will take place during the daytime with some nighttime hours and will be enclosed with temporary soft delineators/fenced-in plywood barriers. Stage 3 construction, located just north of the fare gates is expected to begin the morning of Thursday, March 28, 2019.

You will see construction equipment accessing the site such as scissor lifts, drill rigs, concrete pump/hose and trucks, and temporary scaffolding/structures. Earthquake Safety construction consists of seismic retrofit work performed on each footing and pier cap (a beam connecting two columns) that serves to support the BART trackway under the alignment. 

Stage 1 Closure:  Construction continues behind the escalator located on the south-end of the Concourse, allowing for patron use to and from the Platform for approximately 2 more months. 

Stage 2 Closure:  Construction requires temporary closure of the southwest stairwell for approximately 4-6 months. 

Stage 3 Closure:  Construction is expected to begin Thursday, March 28, 2019 in the area located north of the fare gates and west of the pedestrian tunnel. This work activity will begin with heavy drilling that will make noise.  Sound barrier blankets will be in place to minimize noise levels.  Noise, dust and odors will be monitored, and local regulations will be enforced. All dates are approximate and subject to change.

Add fare and parking machines, restrooms, elevators, escalators, and stairs – except the southwest stairwell, will remain accessible (open) during Stage 2 and 3 construction.  Please watch for directional signs and allow for additional travel time, through the Concourse and between the Concourse and Platform.  Similar earthquake safety retrofit construction is underway at Fruitvale Station.

Seismic retrofit construction continues outside Coliseum Station on both the north and south-end of the Station, mainly off San Leandro Street. Temporary relocation of ADA and BART parking located on the westside (San Leandro Street side) of the station continues.  Construction outside the station on the south-end is nearing completion.                                                                                                                             

We recognize the inconvenience and appreciate your patience and cooperation during this work.  As always, safety is BART’s top priority.  Please proceed around construction areas with caution and watch for signs with safety information and other notices.  Please be advised that changes/modifications may be required at any time; the construction team will make every effort to minimize inconveniences.  Our aim is to complete seismic retrofit work as quickly as possible, while maintaining BART service.
