Sand Creek Road Interchange

The project will expand the highway from two lanes to four lanes (two in each direction) from Lone Tree Way to Sand Creek Road. The project also includes the construction of the Sand Creek Road Interchange and the newly added westbound Sand Creek Road undercrossing, and will provide a median wide enough to accommodate mass transit in the future (eBART).
