Drinkwater Bridge and Underpass Repair Work


Project Information

Due to concrete deterioration found during ongoing inspection work on the Drinkwater Bridge and Underpass, the underpass is now closed. Additionally, access over the top of the overpass, which is on Civic Center Mall, will be closed to all activity. Please use caution when traveling in the area and adhere to all barricades and restrictions. All restrictions will remain in place until the structure can be reinforced.

Construction work will begin in December 2018 to build a new supporting wall below the structure and fill in the open area of the bride deck.  The construction work will cost $6.626 million and is scheduled to be complete during the fall of 2019.

Project History

The Drinkwater Bridge was constructed in the mid 1980’s creating the Civic Center Mall area which has evolved as the City’s civic and arts headquarters. The structure supports open space including grass and trees, the LOVE statue and the fountains which were installed as part of the bridge project.

In early 2014 staff was notified that there were sections of failing concrete located under the structure and as a result contracted with Caruso Turley Scott (CTS) to investigate the cause of the failing concrete. The findings revealed several areas of the structure that are failing due to water intrusion through the deck, due to leaking within the fountain structure, irrigation of landscaping and an insufficient drainage system, and waterproofing membrane that has exceeded its service life.

On June 12, 2018, the City Council authorized funding for repair work and hired Haydon Building Corporation to begin an investigative effort to determine the extent of the immediate repairs necessary. During the investigation, large areas of loose concrete were discovered along the west side retaining wall, in addition to the deterioration of the concrete columns within the center of the structure. Haydon Building Corporation was authorized by staff to remove all loose concrete on the retaining wall and columns, however, during their work the two columns were deemed too unstable for any further investigative effort.

On October 16, 2018 the City Council approved $6.626 million to repair the overpass.  The first phase of will include securing the structure to repair existing damage and prevent future damage. A second phase of improvements will design and construct a waterproofing and drainage system for the bridge that will support the future Civic Center improvements identified in the recently approved master plan update.
