Caltrans says it will spend $1 billion over the next four years installing bike and pedestrian lanes across California and in San Diego. One of the projects is finishing up in Carmel Valley where Caltrans is extending a bike path under Interstate 5. Riders along the bike lane between State Route 56 and Interstate 5 have been dealing with detours lately, and currently, they have to share Carmel Valley Rd with vehicles. “It’s tight and it's dark. It's under the freeway. It scares me to death. I walk my bike through there all the time,” said one bicyclist in the area. When the work is complete, the tunnel under Interstate 5 will connect the two bike paths and allow bicyclists to avoid traffic.
