I-20 @ I-285

complete

The proposed project will improve the operation of the I-20 EB to I-285 ramp with striping and signing upgrades. The project has a total project length of 2.37 miles. Also, the project will separate all of the I-285 ramp traffic from I-20 EB mainline traffic before the exit ramps develop, forcing drivers to make lane decisions earlier, thus reducing the late weaves and impacts on I-20 EB traffic. This will be done by modifying the current lane configuration to 4 lanes approaching the interchange, and at approximately a ¼ mile before the I-285 SB Exit the configuration will split to 5 lanes, with 3 through lanes and 1 EXIT OPTION lane and 1 EXIT ONLY lane. The new EXIT OPTION lane will subdivide to have 1 EXIT ONLY lane to I-285 SB & 1 EXIT ONLY lane to I-285 NB. This new EXIT-ONLY lane for I-285 NB will run parallel to the I-20 EB through lanes, and will be barrier separated from the I-20 EB through lanes. The barrier would begin at the I-285 SB exit and continue to the I-285 NB exit.
