About the Project
The project reduces congestion and improves traffic by adding one general purpose lane (regular lane) in
each direction on SR-55 between I-5 and SR-22 and provide operational improvements at various locations
on SR-55 between SR-22 and SR-91. The environmental phase of the project is complete, and a Build Alternative has been selected that will:
- Add one regular lane in each direction between I-5 and SR-22;
- Modify southbound on- and off- ramps at Katella Avenue;
- Modify southbound off-ramp at Lincoln Avenue; and
- Modify northbound and southbound off-ramps at Fourth Street
Caltrans has prepared and approved the Final Environmental Document (FED), detailing the Preferred Build Alternative. To receive an electronic copy of the FED, please email SR55info@octa.net.
