The Delaware Department of Transportation announces that state Route 1 northbound will be reduced to two lanes from the Biddles Toll Plaza to the approach of the Roth Bridge for ongoing US 301 construction beginning Sept. 24.

The change will be implemented in the overnight hours and this lane reduction will remain in place until the project concludes at the end of 2018.

Motorists using the cash toll lanes will merge into one lane coming out of the toll plaza before merging left into the two existing northbound lanes.

Upon completion of the project, additional lane modifications will be implemented for the tie-in of the new interchange.
