Interstate 110 Ramp Improvements

T-7

Observation

The entry and exit ramps to and from Interstate-110 in Downtown Baton Rouge were designed to facilitate the one-way street system, allowing for expedient movement of commuter motorists into and out of Downtown in the morning and afternoon.

Discussion

As streets Downtown are returned to two-way operation, these ramps must be reconstructed to allow movements in all directions. A typical example of the current configuration is the Florida Boulevard off-ramp from Interstate-110 northbound. The motorist is routed off of the freeway toward the Downtown core, only to be shunted to the east, away from Downtown destinations. These situations, evident at all locations identified in Exhibit A, should be corrected through the reconstruction of the ramps. Signalization of these reconstructed ramp terminals can be accomplished through synchronization with the adjacent signals, preserving vehicular progression along the surface streets Downtown. Reconfiguration of the curved ramps to a 90-degree intersection with the surface street should correct the current mobility deficiency.

Recommendation

The Interstate-110 ramps at North Street, Florida Street, and Convention Street should be reconfigured to allow for two-direction access from the intersected surface street.
