Recent Progress
This project is in the Preliminary Engineering and Environmental Assessment phase. The new interchange configuration is now a partial clover leaf. In February, the interchange design was modified slightly to incorporate a new loop ramp to I-5 northbound. A Findings and Order Document is being developed to address the comments recieved at the Access Hearing and there will be a public review period for this document this summer. Geotechnical drilling is complete and a geotechnical report is being prepared. The bridge design for this project is continuing.
