State Route 77 (SR-77) is a state highway in the U.S. state of Utah, running west and south from Springville across I-15 to SR-147 in rural Utah County.
SR-77 begins at an intersection with SR-147 north of Benjamin. It heads north on 3200 West through Lake Shore, and after a few turns near the shore of Utah Lake, and a bridge over the Spanish Fork, ends up eastbound on 4000 South. The route enters Springville as it curves into 3900 South, crossing I-15 and becoming 400 South in that city's grid. After crossing over the Union Pacific Railroad's Provo Subdivision (ex-D&RGW), SR-77 ends at US-89 (Main Street) near downtown Springville. The entire route is within the flat Utah Valley, rich farmland that was once the bed of Lake Bonneville.
The state legislature designated State Route 228 in 1941, beginning at SR-147 west of Spanish Fork and heading northwest on Palmyra Drive via Palmyra and south on 3200 West to SR-115 at Benjamin. A new State Route 77 was created by the State Road Commission in 1962, connecting the planned I-15 to SR-1 (US-89) in Springville. The legislature deleted SR-228 in 1969, but the north–south piece became part of an extension of SR-77, along with a portion of 4000 South connecting the I-15/SR-77 interchange to former SR-228.
