I-5 HOV Extension: Lomas Santa Fe Interchange

The I-5 Lomas Santa Fe Interchange Project (Unit 1) extended the existing HOV lane in each direction from just south of Via de la Valle to just south of Manchester Avenue and modified the Lomas Santa Fe Drive interchange. The work is expected to relieve congestion on the freeway by allowing carpools to continue through the area, which is heavily congested daily. Two new loop-style on-ramps were added to the Lomas Santa Fe Drive interchange to allow access onto the freeway from either direction. The new ramps will eliminate the left turns to the on-ramps that frequently cause congestion on city streets. The project is part of a plan to construct 10 miles of HOV lanes from the Mira Mesa Boulevard area on I-805 (Unit 2) to Manchester Avenue on I-5.  

The cost of the project was $66 million, funded by the Corridor Mobility Improvement Account (CMIA) and TransNet. CMIA funds were allocated from the transportation bonds voters passed in November 2006 and TransNet funds came from the local half-cent sales tax also approved by voters.
