Interstate 8 / Imperial Avenue Interchange
Caltrans has received funding to move forward on reconstructing the interchange at Imperial Avenue and Interstate 8 (I-8) in the city of El Centro. Work will include constructing two ramps at I-8 that will provide direct access to southbound Imperial Avenue and will provide connectivity to the south portion of the city. The improvements will complement city plans for future commercial and residential development.
Meeting Traffic Demands
Traffic in the project area is primarily associated with the growth in international trade and travel between the United States and Mexico as well as travel onto and from Imperial Avenue north of I-8. The Imperial Avenue interchange experiences congestion in the morning and afternoon hours. Approximately 16,000-27,000 vehicles per day use this section on I-8. By 2025, traffic on this portion of I-8 is projected to almost double.
The $44 million project is funded through the State Regional Improvement Program and the Federal High Priority Projects Program.
- Provide access from Interstate 8 (I-8) to southbound Imperial Avenue-- planned to be extended south of the freeway by the City of El Centro, and eliminate the current out-of-direction travel on city streets and county roads;
- Improve traffic safety by updating the existing interchange; and
- Reduce traffic congestion at Imperial Avenue and 4th Street interchanges on I-8 in the city of El Centro.
Project construction began April 2020 and is scheduled for completion early 2023. The I-8 Imperial Avenue Interchange is expected to open to traffic mid-2022.
