Casper motorists can expect delays at the intersection of Conwell Street and Second Street on Wednesday.

Beth Andress with Keep Casper Beautiful says crews with the city of Casper’s streets division will replace a traffic signal box at the intersection starting at 8:30 a.m. She says the work will likely continue through the duration of the day.

Andress says, while the city works on the signal box, the intersection will be controlled by temporary stop signs. Traffic along Second will also be reduced to one lane in both directions.

Access to Wyoming Medical Center’s emergency room from Second will be maintained during the upgrade.

Andress says the new signal box will allow for the future installation of left turn lights at the intersection.
