THIS SIGN IS NOT REAL
The Locust Street exit is the only non-reverse ramp exit off U.S. 20 west in the interchange. Travellers heading to downtown can use this exit to gain uninterrupted merge access with Locust Street northbound. A signal controls the left-turning southbound Locust traffic at the bottom of the ramp.
