San Lucas is a small community located in Salinas Valley of Monterey County along Union Pacific Railroad. Modern US Route 101 and California State Route 198 both bypass San Lucas along alignments opened during 1972. The original alignment of US Route 101 was carried on Legislative Route Number 2 via a western frontage of San Lucas now known as Cattlemen Road. California State Route 198 originally followed Mary Street via Legislative Route Number 10 into San Lucas and Main Street. From Main Street California State Route 198 crossed the then Southern Pacific Railroad where it terminated at US Route 101 at the intersection of Cattlemen Road and Lockwood-San Lucas Road. Depicted above as the blog cover is a view from Cattlemen Road and Lockwood-San Lucas Road looking east to where California State Route 198 once began.
