There is still a little market to resupply. Awesome muffins! Just go past the gas pumps and you can't miss it.

This spot used to be Rainbow Oaks Country Market, but it is now Rainbow Oaks Restaurant. It offers full-service meals.

March 23, 2025, Lilac Bridge

Built in 1978 at a cost of $1,500,000. Its main span is 455 feet (139 m), with a total length of 745 feet (227 m). The bridge's high arch and sleek design are considered iconic and have won several national design awards. In order to comply with interstate grade laws, they had to cut and blast away everything below us.This hill is made of granite which is very hard to remove. ยพ of a million cubic yards of solid granite was removed. The bridge could have been placed a mile or two down the road for a fraction of the coast but the architect wanted to create something iconic and inspiring.

A great spot to stop for a mid ride snack and restroom break in the middle of the cycle. The San Luis Ray Bike Path starts here too.
