Interstate 505 (I-505) is an interstate highway in California between Interstate 80 in Vacaville and Interstate 5. I-505 is primarily a rural interstate, but travels through Vacaville and the town of Winters. The interstate is the primary route connecting the San Francisco Bay Area and the northern Sacramento Valley, bypassing Sacramento and its attendant city traffic. It also connects the Bay Area to major northwestern cities such as Portland and Seattle.

This route is part of the California Freeway and Expressway System[2].

Power lines connecting Path 15 to Path 66 follow the highway for a while, until one heads northeast and the other northwest.
