PRINCETON, W.Va. — The speed limit will remain at 55 mph through the winter months on a stretch of Interstate 77 from Princeton to Bluefield, the state Department of Transportation announced Wednesday.

The nine-mile stretch has been the site of a major rehabilitation project in recent months. The work is essentially done with the exception of some shoulder work and guardrail installation, transportation officials said. They are keeping the reduced speed limit in place until all of the work is done.

All four lanes are now open and there are no other lane closures scheduled, officials said.

The Princeton to Bluefield project has been part of approximately 60 miles of interstate the state has been rehabbing this year as part of the Roads to Prosperity program. The project included taking off all of the asphalt to the base of the highway repaving with several new inches of asphalt.

The project also included a northbound truck detour on U.S. Route 460 between Bluefield and Princeton.
