EL CENTRO, Calif.—Crews will close the eastbound Interstate 8 (I-8)/Imperial Avenue on- and off-ramps beginning Monday at 9 p.m. for eight to 10 months, according to Caltrans.
The work is part of Stage 1 construction on the I-8/Imperial Avenue Interchange Project that began this spring.
During the extended closure, motorists on eastbound I-8 wanting to access Imperial Avenue will be detoured along 4th Street/State Route 86 (SR-86) located east of Imperial Avenue.
The westbound I-8 on- and off-ramps will remain open for this first stage of work; however, both eastbound and westbound ramps of the I-8/Imperial Avenue Interchange will be closed one or two nights the week of July 20 to demolish and remove the bridge. More details will be provided prior to the closures.
Motorists will be detoured on adjacent interchanges and city streets during the full interchange closures.
Recommended detours maps for both closures can be found at https://dot.ca.gov/caltrans-near-me/district-11/current-projects/i8-imp-interchange.
Loud construction work will be scheduled during the day as much as possible with three months of noisy pile driving work. The nighttime bridge demolition will also be loud but is only expected to take place one or two nights at a time, as needed.
Crews will work to reduce noise and dust as much as possible during construction. Caltrans and the City of El Centro will monitor detour traffic to minimize delays.
Motorists are reminded to plan for possible delays, slow down, watch out for construction personnel and equipment and Be Work Zone Alert.
The I-8/Imperial Avenue Interchange project will remove the existing bridge and eastbound on- and off-ramps, then reconstruct the structure and the on- and off-ramps in both directions.
Construction will include a new entrance loop ramp from southbound Imperial Avenue to eastbound I-8 and create access to the City of El Centro’s upcoming extension of southbound Imperial Avenue to city areas south of I-8.
Stage 2 work on the northern portion of I-8 is anticipated to take four to six months to complete and could begin as early as December. During Stage 2, all I-8/Imperial Avenue on- and off- ramps will be fully closed. The interchange is expected to open to traffic by the end of 2022 with project completion by mid-2023.
The total project cost is approximately $44 million with $42 million funded through the Regional Improvement Program and another $2 million from the Federal Highway Priority Projects Program.
The construction schedule is subject to change based on weather and other unforeseen factors.
