WHAT IS THE 11TH STREET BRIDGE PROJECT?
The 11th Street Bridge crosses the Union Pacific Railroad (UPRR) tracks and North MacArthur Drive in the City of Tracy. 11th Street is one of the City’s main east-west corridors that serves local, truck and commuter traffic. The project replaced the bridge to enhance pedestrian, bicycle, and vehicular safety and continued to efficiently serve users.
WHO WAS RESPONSIBLE FOR THIS PROJECT?
The City of Tracy was the lead agency working in partnership with Caltrans and San Joaquin County.
WHAT IS THE PURPOSE OF THE PROJECT?
The old bridge was originally built in 1936 as a two-lane facility and then later widened to four lanes (two in each direction) in 1960. The condition of the old bridge deteriorated with time and needed replacement in order to meet the latest structural and seismic requirements. The project replaced the old bridge to provide a safer crossing over the UPRR tracks. The construction cost for this project was approximately $46 million and was funded through the Highway Bridge Program (HBP), Local Seismic Safety Retrofit Program (LSSRP) and City of Tracy Transportation Funds.
WHAT WORK WAS DONE TO THE BRIDGE?
Work on this project included the following activities:
- Replaced the existing 1,441 foot long bridge over the UPRR tracks with a shorter structure in combination with retaining walls and embankment fill at the approaches
- Constructed a two-lane temporary bridge on the south side of 11th Street
- Removed the existing bridge and constructed the new bridge
- Modified the signalized intersection of North MacArthur Drive and 11th Street
- Relocated existing utilities
WILL ACCESS TO THE 11th STREET BRIDGE BE COMPLETELY CLOSED DURING CONSTRUCTION?
During stage one, a temporary two-lane bridge was constructed to maintain access during the bridge replacement. To minimize impacts to the traveling public, pedestrian, bicycle, and vehicular traffic was detoured to the temporary bridge while the new bridge was constructed.
HOW WAS THE PROJECT CONSTRUCTED?
Construction for the project was planned to be completed in stages to minimize impacts and maintain mobility for local and regional travelers. The plan included:
- Stage 1: Construction of temporary bridge / traffic switch from existing to temporary bridge
- Stage 2: Demolition of old bridge / construction of new bridge facility
- Stage 3: Intersection and signal improvements, roadway work / bridge opening
ARE THERE ALTERNATIVE ROUTES TO AVOID THE CONSTRUCTION AREA?
Yes, the City recommended taking I-205 to N. MacArthur Drive exit or I-5 exit to 11th Street, using Grant Line Road to N. MacArthur Drive.
WHEN DID CONSTRUCTION START AND HOW LONG DID IT LAST?
Construction began in April 2015 and concluded in summer 2018.
DOES THE NEW BRIDGE INCLUDE A BICYCLE LANE?
As part of the project, the shoulders of the bridge was striped to be 8’ wide and serve as Class 2 bicycle lanes.
WHAT CAN I EXPECT DURING CONSTRUCTION AND HOW WILL THIS PROJECT IMPACT ME?
Access to businesses and residences remained open during construction. Local property owners and the traveling public may experience traffic delays and the City recommended use of alternative routes during construction. In addition, typical construction related noise may be experienced during scheduled working hours.
WHEN DID THE WORK TAKE PLACE?
Construction generally occurred Monday through Friday from 7:00 a.m. to 3:30 p.m. Anticipated night and weekend work was approved by the City.
