DEMOPOLIS &8212; The construction along U.S. Highway 80 in Demopolis should result in significant improvements in the roadway, an Alabama Department of Transportation official said. Tuesday.

The work encompasses 4.28 miles of highway and is expected to take 80 working days to complete.

The project will improve the intersections along the highway and level out areas in the road bed. Workers will also replace the traffic stripe.

The work stretches from the north end of the Black Warrior River Bridge and the intersections of U.S. Highway 80 at Walnut Street, Bailey Road and Floyd Street, according to documents from ALDOT.

The project costs $1.3 million, and is being completed by the Bunn Construction Company out of Tuscaloosa. The work is part of a project that will eventually extend Highway 80 as a four-lane from Montgomery to the Mississippi state line, a project that will cover some 22 miles over the next 10 years, Harris said.
