About I-5 North Coast
The 26-mile project will add highway lanes and operational improvements to provide mobility choices for motorists on I-5 in the northern San Diego region. The project area extends from La Jolla Village Drive (I-5) and Mira Mesa Boulevard (I-805) to Vandegrift Boulevard, and includes widening this area for new managed/high-occupancy vehicle (HOV) lanes for transit and carpools. Total available funding as of 2005 for operational and additional highway lanes is estimated to be $1.4 billion. Estimated project costs for the operational improvements are $28.7 million for extending the northbound HOV lanes from Via de la Valle to Manchester and $31.7 million for adding auxiliary lanes and improving the interchange at Lomas Santa Fe Drive.
This has been identified as a high-priority project by SANDAG and is part of the TransNet Early Action Program.
