Night Work on I-5: In January, crews began work on the viaduct – a bridge structure that will carry the Trolley down I-5. This work is focused within the median of I-5 and requires intermittent lane closures. To prepare for this construction, crews have demolished the median and restriped traffic lanes on both northbound and southbound I-5 between the Nobel Drive and La Jolla Colony Drive exits. Drilling work in the median and along the sides of I-5, from La Jolla Colony Drive to Voigt Drive, starts in late March 2018.

This work is focused on Genesee Avenue, from Regents Road to Nobel Drive. Northbound and southbound lanes of Genesee Avenue will be restriped and shifted to the outer lanes from Regents Road to Nobel Drive while crews begin work in the median. Large drilling equipment will be set up within the median. Traffic control phasing and lane configuration may vary between day and night work hours.

Friars Road: In fall 2016, crews began work along Friars Road between Sea World Drive and Napa Street to build the San Diego River Bridge Double Track project in advance of construction on the Mid Coast Trolley project. Several traffic control phases involving multiple lane closures and shifts will be implemented in this area throughout the course of the project to help facilitate this work. The concrete barrier railing that has been placed on Friars Road is to support both projects and also is expected to last throughout the project duration.
