Here’s what you need to know about the Airport Boulevard interchange construction at Highway 101 that begins tonight:

Crews will begin construction at 7 p.m. June 3, working 7 p.m.-6 a.m. Monday through Saturday for several weeks. The first phase involves building new on- and off-ramps  at the Airport Boulevard interchange north of Santa Rosa, and replacing the current two-lane overcrossing with a new five-land bridge.
