Fabrizi Trucking and Paving will get the $7.05 million job, which will widen Route 42 from where it narrows near Drake Road south to the city limits at Boston Road.
The total project is estimated at $11.5 million, including property acquisition.
Fabrizi was the lowest of four bidders for the project.
The Ohio Department of Transportation awarded the city $6 million for the work, and the Northeast Ohio Areawide Coordinating Agency came up with almost $1 million, city officials have said.
Also, Ohio is offering the city a no-interest $2.3 million loan.
It will be enough to get the job done, according to Mayor Tom Perciak, who said the city will probably take short-term notes to cover the rest.
Perciak has been pushing for the widening since the day construction wrapped up on the previous section, which added lanes from the post office to a point south of Drake Road.
The city has spent the last year acquiring right of way for the project. Construction is expected to start later this fall and take about a year.
