Why not make all the tourists ride bikes. Put up a gate at the tunnel, resident cars only.

Construction on the Holman Highway Roundabout project is expected to begin in June. The project, up at the intersection of 17-Mile Drive and state Route 68, will likely push a lot more vehicle traffic onto Lighthouse Avenue, a Monterey artery that is already frequently clogged.
“Come 3 p.m., 3:30 p.m., it starts to back up, and from that point until about 7 p.m., it’s pretty slow here,” said Jason Costanza, who owns Monterey Seibuken Academy, on Lighthouse Avenue.
Monterey is hoping rather than getting frustrated with even more traffic this summer, people will take a new route to work.
“We want to get people to walk, and we want to get people to bike,” said Andrea Renny, with the city’s traffic and engineering department.
