The state Department of Transportation's Route 110 redesign project in Halesite is 75 percent done, officials said.
In spring 2012 the state started a drainage and roadway improvement project to mitigate flooding and improve mobility and safety for motorists in the low-lying North Shore coastal area. The project, first proposed to cost about $18.1 million, has cost about $21 million.
"We're near the end of the project," Eileen Peters, DOT spokeswoman, said Tuesday. "We have done all of the roadwork; we completed all the drainage improvements, the curbs, the sidewalks, paving."
As part of the 2-year-old project, a portion of Creek Road off Route 110 near Hill Place has been closed for about a week, except to local traffic, to install drainage and relocate a sewer pipe. Officials say the latest road closure should end by Friday; and Peters said the entire project should be completed by the end of the summer.
"It took a good deal of design work to develop a solution that would relieve the constant flooding," Peters said.
Some of the improvements include raising Route 110 about a foot, from Hill Place to Mill Dam Road, to help prevent flooding; installation of traffic circles at Creek and Mill Dam roads; replacement of old and deteriorated culverts; upgraded signs and crosswalks, and alterations to improve navigation by pedestrians and bicyclists, Peters said.
The major work that remains includes the installation of four tide gates on Creek Road, finish cleaning and reshaping the creek and the building of a retention basin that will look like a pond, Peters said.
Al Salese, who owns Junior's Pizza on New York Avenue, which has been in the area for 32 years, said there were some minor inconveniences but it ultimately was worthwhile.
"The circles look great, the traffic moves well," Salese said Tuesday. "The construction really wasn't terrible. The changes actually make the area look so much better."
