Business Loop I-5 - Woodland

The California State Highway System Signing Log (October, 1991) references Business Loop I-5 in Woodland from "Interstate 5 and Main Street under crossing over Main Street and SR 16 (CR 98) to Interstate 5 at the CR 18 over crossing." Business Loop I-5 follows portions of old U.S. 99W and the old alignment of SR 16 (Main Street) across the city. The L-shaped route commences a 6.4 mile long route at Exit 537. The north to south leg doubles as SR 16 and CR E7 to the end at Exit 540.

Signs for the Woodland business route are sporadic but the turn at Main Street and Road 98 is marked.
