temporary two-lane bikeway located on the outside shoulder of the northbound

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.

Crews also began construction on the viaduct - a bridge structure that will carry the Trolley down the middle of Genesee Avenue. 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. Traffic control signs, including necessary detours for motorists, pedestrians and bicyclists, will be posted. These types of traffic controls will be deployed at various times through early 2020.

Gilman Drive Bridge: Work began in late 2016 on I-5 near Gilman Drive to prepare for construction of the Gilman Drive Bridge. Crews have installed temporary barricades near Gilman Drive that will remain for approximately two years. The new bridge will connect the west and east sides of UC San Diego and span I-5.
View additional information.
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.
