SR 140 FROM SR 400 NB RAMPS TO OLD ALABAMA ROAD

complete

The proposed quick operational improvement project would consist of corridor improvements to optimize throughput along SR 140. This project proposes to widen the SR 400 northbound ramps to two lanes to tie into a dual right turn configuration at the ramp terminal, shift the two SR 140 eastbound through travel lanes to the south and signalize this ramp terminal with a two phase signal. The project will also extend the turn lane storage for SR 140 traffic turning left to the SR 400 southbound on-ramp using the existing concrete median. In summary, a a right turn lane will be added to the existing SR 400 northbound ramp 7A, extending the westbound left-turn lane to southbound SR 400, and install/modify the existing traffic signal at the northbound ramp terminus. The project will also reconfigure the existing pavement and median to remove the “trap” lane on the eastbound SR 140 approach to the Old Alabama Road intersection.
