That's according to Le Mars City Administrator Scott Langel.
The project involved widening and resurfacing the highway beginning about 50 feet east of the Highway 3 bridge over the Floyd River to 600 feet east of the Ninth Avenue intersection.
In addition, the project added right-turn lanes at the entrance to the Riverview Ball Complex and at 16th Avenue Northwest.
Since the end of April, traffic has been detoured around the project, which has temporarily eliminated one of the three entrances to Le Mars from the Highway 75 Bypass.
This week, Barkley Asphalt is in town paving two layers of asphalt on Highway 3 from the Highway 75 Bypass interchange to Business Highway 75.
"I would guess they should be done by the end of the week or Monday," Langel said. "Once they pull out, then the asphalting work will be done."
Once the paving is done, several additional aspects of the project must be completed to open the roadway, the city administrator said.
Those include minor grading along the roadway, placing of topsoil, installing signs, marking the pavement and removing the traffic controls used during construction, he said.
Langel said this might take until the end of next week, but he planned to ask contractors if it would be possible to finish the work early and open the highway as soon as Wednesday.
Wednesday is the first day of the Plymouth County Fair, which draws thousands of people each of its five days.
If the Highway 3 work is not complete, drivers will need to continue to use the detour, which takes traffic north to the next Le Mars interchange and then south into Le Mars.
A portion of recreation trail to be added near this Highway 3 project likely won't be completed this year, Langel said.
That project will add to the existing recreation trail and make a path that allows pedestrians to cross the Floyd River.
It will stretch from 16th Avenue Northwest and run near the north side of Highway 3, through Riverview Park and under the first portion of the Highway 3 Floyd River bridge, then will come up on the south side of the highway and cross the bridge on the south side, heading into Le Mars.
Work on the project had been delayed due to federal wetland requirements, which involved changing some of the project plans, Langel said.
The recreation trail connection project will likely be put to bid in November and completed next year, he said.
However, grading for the project may be completed in time for this fall's seeding, Langel noted.
