Southbound lanes partly closed.

As part of the U.S. 301 toll road project, a section of northbound Route 1 will be closed at night from Dec. 1 to Dec. 6 and some southbound lanes will be closed as well during the same time frame.

The closures, all north of Middletown, are necessary for the installation of structural components of the new U.S. 301 bridge over Route 1.

As announced by the state Department of Transportation, Route 1 northbound will be totally closed between Pole Bridge Road and the U.S. 13 free ramp at the following times:

*8 p.m. Friday, Dec. 1 until 7 a.m. Saturday, Dec. 2;

*8 p.m. Saturday, Dec. 2 until 7 a.m. Sunday, Dec. 3;

*8 p.m. Sunday, Dec. 3 until 5 a.m. Monday, Dec. 4;

*9 p.m. Monday, Dec. 4 until 5 a.m. Tuesday, Dec. 5;

*9 p.m. on Tuesday, Dec. 5 until 5 a.m. Wednesday, Dec. 6.

During the nighttime closure, the tolls on northbound at the Boyds Corner toll plaza will be waived, said a DelDOT news release.

The detour will be Pole Bridge Road to U.S. 13 northbound and return to Route 1 northbound. Detour signs will be posted for motorists.

There will also be lane closures on southbound Route 1, between U.S. 13 southbound and Pole Bridge Road during roughly the same time frame. But the lane closures won’t mean the entire southbound Route 1 will be closed. One or more lanes might be closed, not that entire stretch of road, a DelDOT official acknowledged in an email.

The lane closures for southbound Route 1 are:

*8 p.m. Thursday, Nov. 30 until 5 a.m. Friday, Dec. 1;

*8 p.m. Friday, Dec. 1 until 7 a.m. Saturday, Dec. 2;

*8 p.m. Saturday, Dec. 2 until 7 a.m. Sunday, Dec. 3;

*8 a.m. Sunday, Dec. 3 until 5 a.m. Monday, Dec. 4;

*9 p.m. Monday, Dec. 4 until 5 a.m. Tuesday, Dec. 5;

*9 p.m. Tuesday, Dec. 5, until 5 a.m. Wednesday. Dec. 6.

Northbound Route 1 will have lane closures between Pole Bridge Road and the U.S. 13 free ramp from 8 p.m. on Thursday, Nov. 30, until 5 a.m. on Friday, Dec. 1.

When completed, the new U.S. Route 301 toll road will start where the existing 301 crosses into Delaware from Maryland. The new road runs parallel to the existing 301 and then moves east of 301 and connects to Route 1 just below the Roth Bridge at the C & D Canal.

“The U.S. 301 mainline project is progressing nicely,” said Ken Cimino, spokesman for the project. “All of the contracts are on schedule or ahead of schedule for the December 2018 opening and collection of tolls.”

Overall, the project is about 60 percent complete with one full construction season left, he said.

“We haven't had any setbacks and I don't anticipate this winter being too big of a factor at this time,” said Cimino.
