A Delmarva Power project will intermittently close portions of U.S. Route 13 and Del. Route 1 north of Smyrna on Sunday morning.
The installation of a fiber optic cable over the roadways will require intermittent, rolling road blocks on both roadways, just north of the Smyrna Rest Area and Information Center, from 6:30 a.m. to 10 a.m.
Intermittent lane closures also will occur on Route 13.
At the same time, the southbound exit off Route 1 to Route 13 (Ramp 119A) will be closed. During those hours, traffic will be directed to Ramp 119B.
Delmarva Power says the new cable will enhance electric service reliability by improving communications with the utility's operations center.
