As with most passes in the California Coast Ranges, it is not very high when compared to those in other mountain areas within the state. The road that traverses Pacheco Pass is State Route 152, which runs for between SR 1 in Watsonville and SR 99. Pacheco Pass Road, the western section between Gilroy and the pass itself (a distance of approximately 14 miles), is a two-lane highway from Gilroy to the junction with SR 156 and a four-lane highway over the pass; it has been the site of many accidents.
