FILE PHOTO 2020- Caltrans crews use excavators with breaker attachments to demolish the Imperial Avenue interchange bridge that connects to Interstate 8 Thursday evening, July 23, in El Centro. 

 Detours at Forrester Road and SR-86/4th Street

EL CENTRO — Full freeway closures on Interstate I-8 (I-8) between Forrester Road and State Route 86 (SR-86)/4th Street are scheduled for four consecutive nights beginning Monday for the I-8/Imperial Avenue Interchange Project.

Construction crews will close all lanes on eastbound I-8 from Forrester Road to SR-86/4th Street Monday from 9 p.m. to 5 a.m. to install falsework. One lane of westbound I-8 will also be closed during this time with the remaining westbound lanes open to traffic. 

Crews will close all lanes of the westbound I-8 section Tuesday and Wednesday from 9 p.m. to 5 a.m.

 The same stretch of eastbound I-8 will be closed overnight Thursday, April 1 during the same time.

 Detours are as follows: 

  • Detour for eastbound I-8 closures: Eastbound traffic will be detoured to exit at Forrester Road and travel north to Evan Hewes Highway east to SR-86/4th Street south to the I-8 connector.
  • Detour for westbound I-8 closures: Westbound traffic will be detoured to exit at SR-86/4th Street and travel north to Adams Avenue/Even Hewes Highway west, to Forrester Road south to the I-8 connector.

The recommended detour maps for the full interchange closure can be found at https://dot.ca.gov/caltrans-near-me/district-11/current-projects/i8-imp-interchange.

Access to businesses and medical facilities will continue via the detour.

The I-8/Imperial Avenue Interchange Project removed the existing bridge and eastbound on- and off-ramps and will 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. Project construction began spring 2020 with Stage 1 closures of the eastbound on- and off-ramps beginning that July. Stage 2 closure of the entire interchange began December 2020 with reopening expected late summer 2021.
