The SR-178 Widening project consisted of widening the existing two lane highway to three lanes in each direction with paved median and shoulders from Canteria Drive to Masterson Street, and to two lanes in each direction with paved median and shoulders from Masterson Street to Miramonte Drive. The project also included installing traffic signals at the SR-178 intersections with SR-184, and with Masterson Street. Storm drainage improvements and a short section of retaining wall was also included with the project.

TYLIN has provided the engineering design and the design support services during construction for the SR-178 Widening Project.  The project construction was completed in July 2017.  TYLIN has begun finalizing all the close out work needed to transfer this project to Caltrans.  As the progress of reestablishing the right-of-way limits for the new road way is ongoing, the approval process by Caltrans for the new legal descriptions and plat maps are taking longer than expected to finalize.

TYLIN’s current contract will lapse on June 30, 2020.  At this time an amendment is needed to extend the expected completion date to January 31, 2021, allowing TYLIN to finish their scope of work.  No additional funds are needed at this time.

This Amendment is 100% locally funded.  There is no General Fund impact associated with the SR 178 Widening Project.
