Cal Trans begins Hwy 78 upgrades in Escondido

Cal Trans construction crews next week will begin work on a $19 million multimodal project to upgrade about five miles of Hwy 78 between North Broadway and Flora Vista Street in Escondido.

This work was originally going to start on Monday, but the heavy rains delayed it.

Initial work will improve curb ramps for pedestrian access in accordance with the Americans with Disabilities Act. Other work will include vehicle to infrastructure (V2I) traffic signal upgrades, ITS upgrades and a Class III bike route.

Following phases of construction include removal and replacement of the pavement, high visibility striping, utility upgrades, and a shared bike lane. To minimize traffic impacts and increase worker safety, work will typically take place between 9 p.m. to 5 a.m., Sunday through Thursday. This project is expected to be completed in Fall 2021.

The $19 million project is funded through the State Highway Operation and Protection Program (SHOPP).

Nearby residents may hear construction noise related to the work, including backup alarms, jackhammering, and saw cutting. Every consideration will be made to minimize impacts during the course of this much-anticipated project. Detour signs will direct motorists and pedestrians around closures.
