Heritage Road Bridge Replacement
The City of Chula Vista proposes to replace the existing Heritage Road Bridge over the Otay River (between Nirvana Avenue and Entertainment Circle South) and widen a portion of Main Street, between Nirvana Avenue and Heritage Road. Heritage Road Bridge is located 1.8 miles east of I 805 and just south of Main Street, in the City of Chula Vista. The project will construct a new, wider and longer bridge that would allow floodwaters from a 100-year flood event to be contained within the river channel without overtopping the bridge or road. The project also includes reconfiguration of the intersections of Main Street / Heritage Road and Heritage Road / Entertainment Circle North
The proposed project would require the demolition of the existing 54-foot wide by 82-foot long steel girder and timber deck bridge, and construction of a new bridge that would pass a 100-year flood event. The proposed new bridge would be a cast-in-place, pre-stressed concrete box girder with a width of 129’ 4” (6-through lanes, 2-turn lanes, 8-foot shoulders, and 6-foot sidewalks) and length of 450 feet. The bridge would be widened to accommodate 6-through lanes in order accommodate 20-year traffic volumes as determined by the Traffic Analysis prepared for the proposed project. In addition, the proposed project would include a widening of Main Street between its intersection with Heritage Road and Nirvana Avenue to the west, a distance of approximately 3,700 linear feet.
BRG is responsible for environmental clearance (FHWA CE/City MND), and regulatory permitting (CWA Section 401 and 404, and F&G Code Section 1600 Streambed Alteration). We also worked closely with the City of Chula Vista and Caltrans to identify a locally preferred alternative that would be eligible for federal funding.
Once the final design is complete, BRG will obtain the required regulatory permits including a Clean Water Act Section 401 and 404 Permit, California Department of Fish & Game Code Section 1600 Streambed Alteration Agreement, and a City of Chula Vista Habitat Loss and Incidental Take (HLIT) Ordinance Permit.
