Temporary signals are being added on the east side of the I39 bridge because the DOT has two projects happening simultaneously. The first project is a bridge rehab project where they are directing traffic to each side of the expressway to paint and rehab the bridges. They will be also constructing the roundabout this year. This will result in the loss of the eastbound on ramp for a period of time they will be temporarily using the westbound HWY 16 off-ramp for both east and west bound on HWY 16 traffic necessitating the lights at the off ramp.
The future roundabout will be located at HWY 16, 127 (Columbia Dr.), and the southbound I39 on ramp.
