Description

The Delaware Department of Transportation (DelDOT) will modify the existing interchange at State road (SR) 1 and SR72 to a Diverging Diamond Interchange (DDI). DelDOT will evaluate the effectiveness of the DDI from a construction cost, implementation, vehicle user, pedestrian/bike user, traffic operations, and maintenance perspective. DelDOT anticipates that the DDI will provide operational improvements on par with significantly more costly interchange types while being constructed more quickly and with fewer user impacts.
