I-5/SR-56 Freeway Interchange Project
Document Type
NOD - Notice of Determination
Document Description
Caltrans District 11, proposes to improve existing and expected future traffic operations along the Interstate 5 (1-5) and State Route 56 (SR-56) corridors, including Del Mar Heights Road, Carmel Valley Road, Carmel Country Road, and local streets within the Carmel Valley community. The ability to avoid the use of local surface streets in order to connect from onefreeway to the other would improve the efficiency of traffic operations for both local and regional traffic and would facilitate the movement of people and goods. The proposed 1-5/SR-56 interchange project would begin south of the western segment of Carmel Valley Road along 1-5 at post mile (PM) 32.7 and continue to PM 34.8 north of Del Mar Heights Road. Along SR-56, the proposed project would begin at PM 0.0 at El Camino Real and continue to PM 2.5 east of Carmel Country Road. The length of the proposed project is approximately 2.1 miles on I-5 and approximately 2.5 miles on SR-56, for a collective length of 4.6 miles. The alternative selected is the Alternative 4/Hybrid Alternative, single flyover project, as described in the EIR/EIS which includes only one freeway-to-freeway ramp with two general-purpose lanes directly connecting westbound SR-56 to northbound I-5.
