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.

Ocean Beach Bike Path Closures: A closure of the Ocean Beach Bike Path extending from W. Mission Bay Drive to Pacific Highway, which is unrelated to the Mid-Coast Trolley project, is currently in place for an SDG&E project. For more information on that project, please visit sdge.com/major-projects.

Downtown Lane Closures: This spring and summer, nighttime lane closures are planned at five locations in Downtown San Diego as crews work on underground communication systems for the Mid-Coast Trolley. Locations include Cedar Street, Palm Street, Sassafras Street, Washington Street, and Noell Street. Work hours will be Sunday through Thursday, from 9 p.m. to 5 a.m. beginning the week of April 15. Work will occur at one location at a time and last between one week to one month at each location. Please follow detour signage and use caution when traveling near work areas.

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. Drilling hours are Monday through Friday, from 7 a.m. to 5 p.m. Some night work may be required. This median work will be ongoing through late summer 2018.

Balboa Avenue/Morena Boulevard Ramp Closure: Intermittent, nighttime closures of the eastbound Balboa Avenue to northbound Morena Boulevard ramp will be in place until late summer 2018. The closures will be in place to accommodate excavation, utilities construction, and street improvement work. Work hours are Sundays through Thursdays, from 7 p.m. to 5 a.m. each night. Traffic control signs and detours will be posted. Please use caution when traveling near the work area.

Noise Alert on Genesee Avenue: Crews will begin drilling operations on Genesee Avenue from Regents Road to Eastgate Mall in February 2018. Drilling activities will take place during night work hours. Crews will minimize noise impacts as much as possible.

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.

Rose Creek Bikeway Construction: Preliminary construction of the Rose Creek Bikeway began in January 2018. Initial work includes clearing and removing vegetation in the construction area near the creek between Santa Fe Street and I-5.

Friars Road: Crews will be working along Friars Road, between Sea World Drive and Napa Street, to build the San Diego River Bridge Double Track project in advance of Mid-Coast Trolley project construction. Work began in fall 2016 and is expected to be complete in 2019. Throughout the course of the project, several traffic control phases involving multiple lane closures and shifts will be implemented along Friars Road to help facilitate this work.

View map for more information.

Morena Boulevard Construction Activities: In March 2017, Mid-Coast Trolley construction crews began construction along Morena Boulevard from Clairemont Drive to Balboa Avenue. Initial activities include traffic barrier installation, vegetation removal, utility installation, and wall construction for the future light rail infrastructure. To accommodate this work, the southbound lane of Morena Boulevard closest to the railroad tracks (the furthest west lane) will be closed to traffic for the duration of the project. Additionally, various portions of Morena Boulevard between Balboa Avenue and Tecolote Road may be reduced to one lane in either direction throughout the life of the project. Additional truck traffic should be anticipated during this work. Specific locations for lane reductions will vary as crews make progress on the new Trollley line. Road conditions will change throughout the construction process and motorists, cyclists, and pedestrians should use extra caution when traveling near the work area and remain aware of travel speed and road conditions. Work hours are Monday through Friday, 7 a.m. to 5 p.m., although intermittent weekend work will sometimes be required. Traffic controls will remain in place 24 hours a day.

Gilman Drive Bike Lane Near Rose Canyon Bike Path: A portion of the bike lane on Gilman Drive, below the I-5 freeway overpass, will be intermittently closed for project construction access. Cyclists will still be able to access the Rose Canyon Bike Path. Please exercise extra caution when traveling near the work area.

Marian Bear Memorial Park: Crews have fenced off an area within the Rose Creek Channel, near the existing railroad tracks, for construction activities and staging equipment purposes. 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.

Balboa Avenue: Crews continue to work nights to minimize impacts to local traffic. For all residents and businesses in the area, access to driveways will be maintained throughout the project. There may be some portions of roads closed or detoured at night.
