Temporary Realignment of Rose Canyon Bike Path and I-5 Impacts: Starting June 13, 2018, a southern portion of the Rose Canyon Bike Path will be temporarily relocated to the west side of the train tracks, east of Interstate 5 and north of Santa Fe Street, while crews construct a new, permanent path. The interim path will connect the north end of Santa Fe Street to about 1,000 feet north of State Route 52. A temporary realignment of the northern portion of the bike path is also in place, rerouting to a protected, temporary two-lane bikeway located on the outside shoulder of the northbound I-5 off-ramp. Sections of the permanent path will be reopened as they are completed starting in summer 2019. The full, permanent path is anticipated to open in 2020.

Genesee Avenue Traffic Shift: On January 2, 2018, crews began shifting traffic to the outer lanes of Genesee Avenue from La Jolla Village Drive to Nobel Drive. 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.

There will be no access along the Rose Creek channel between Marian Bear Memorial Park and Rose Creek open space. Users of the Marian Bear Park trail should avoid entering or passing through the construction area. Please follow direction of the posted signs.

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.

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.
