The video is a time lapse of the Replacement & Modernization of Marsh Creek Road Bridge. The existing road bridge spanning over Marsh Creek at Clayton, California was deemed “Geometrically Intolerable”. It was decided to replace the existing road bridge with a new 91 ft long Bulb-Tee Girder bridge.

The project envisioned constructing a new precast/prestressed concrete wide flange girder bridge in stages, removing the existing bridge, reconstructing the pavement, widening the creek channel under the new bridge, installing drainage improvements, installing retaining walls, erosion control, signing and striping.

The approximately $5 million project was completed in under a year’s time – made possible by the utilization of Accelerated Bridge Construction (ABC) techniques. This quick turnaround speed, coupled with several other factors such as the local outreach of the project, the challenges, the management process and so on earned the project the National APWA Public Works Project of the Year for 2019 in the Category of Transportation for less than $5 million.
