The $2 million project will extend the right turn lane and add a left turn lane to the southbound US 75 frontage road at Campbell, install a westbound auxiliary lane on Campbell from Alamo Road to Collins Boulevard and extend the left turn lane to allow westbound traffic access Alamo from Campbell.
It will also improve the traffic signal at the intersection of Campbell and Collins.
The project is funded by the city of Richardson, the Department of Transportation and the Federal Highway Administration.
