Motorists in the northwest corner of Jefferson County will see some delays for the next month and a half while crews lay down a new layer of asphalt on two roads in the area.

Work is scheduled to begin on Northwest Boulevard and a portion of New Sugar Creek Road today (Sept. 23).

The work involves a .84-mile section of New Sugar Creek Road from Hwy. 30 north to the St. Louis County line, and the complete .57-mile stretch of Northwest Boulevard between Hwy. 30 and Saline Road.

“The New Sugar Creek project will be a particular headache for some because it is well-traveled,” Jefferson County Public Works Director Jason Jonas said.

That section of New Sugar Creek Road averages 13,060 vehicles per day.

Northwest Boulevard typically sees 7,650 vehicles per day, Jonas said.

Crews from NB West Contracting in Pacific was awarded a $133,767 contract for the work on New Sugar Creek Road and a $104,456 contract for the Northwest Boulevard project. The company submitted the lower of two bids for the work.

Both projects call for the company to lay a thin coat of new asphalt on the road surfaces, seal cracks and joints and make pavement repairs where necessary.

Jonas said work on both projects, scheduled to last 45 days, should not involve any total road closures.

“Even so, on a road as busy as New Sugar Creek, having to take it down to one lane at times during the day may cause some backups,” he said. “But we hope it shouldn’t be too bad.”

Jonas said both roads will remain open to two-way traffic during the afternoon commuter hours and into the night, with work only going on during the day.

“Once the road has been resurfaced, they’ll put some temporary reflectors on the road for a couple of weeks until the asphalt has cured and it can be striped.”

Jonas said that section of New Sugar Creek Road was last resurfaced in 2013, while Northwest Boulevard last was resurfaced in 2017.

The countywide 1/2-cent tax for road and bridge improvements will pay for 20 percent of each project, with the rest coming from the federal government.
