Centennial Boulevard between Fillmore Street and Garden of the Gods Road will be limited to one lane in both direction starting Monday, city officials said.
The "major traffic shift" will allow crews to continue construction between Windmill Avenue and Garden of the Gods Road, the city said in a news release.
Crews will begin to prepare the area Sunday and by Monday morning, the east side of Centennial Boulevard will be closed between Rialto Heights and Garden of the Gods Road.
Also on Centennial Boulevard, traffic will be placed on the west side of the center median to allow reconstruction of the northbound lanes. Northbound motorists will merge into a single lane south of Rialto Heights and southbound motorists will be in a single lane from Garden of the Gods Road through Rialto Heights.
City officials expect delays to take place, especially during peak travel times, once the road work begins.
Sections of Centennial Boulevard between Garden of the Gods Road and Fillmore Street will be under construction this year as part of a $9 million project funded by the Pikes Peak Rural Transportation Authority.
The project's aim is to revamp Centennial Boulevard with a continuous sidewalk on both sides of the road and buffered bike lanes.
