[citation needed] Northbound US 77-L begins as LaSalle Avenue in southern Waco at a traffic circle with its parent route, along with Circle Drive and Valley Mills Drive.

Approximately 0.6 miles (0.97 km) north-northeast of the northbound southern terminus of US 77-L, it connects with southbound US 77 at South 18th Street.

After crossing Interstate 35 (I-35) / US 77 and then U.S. Route 84, the highway drops its freeway status and briefly enters Bellmead.

The highway enters Lacy Lakeview as the town's main street.
