Summerlin Parkway project to go another week

The $2 million Summerlin Parkway improvement project will extend a week beyond its original June 1 completion date, Las Vegas officials said.

The city's Public Works Department announced Monday that construction probably will continue through Sunday as crews fix grade separation problems with a third westbound lane to the freeway, from U.S. Highway 95 to a Buffalo Drive exit.

Jerry Walker, deputy director of field operations for Las Vegas, said Southern Nevada Paving crews ran into problems when they tried to raise the elevation of the westbound Buffalo offramp to meet the height of the newly added third lane.

Workers were surprised to find cemented gravel under the Buffalo offramp instead of dirt fill, Walker said.

Engineers are trying to decide whether or not to remove the cemented gravel before constructing the new exit.

Walker expects that the extra work will add up to $100,000 to the overall cost of the project.

Motorists are advised to use the Durango Drive offramp as an alternate route.
