— Rock County residents will have two opportunities to learn more about a plan to reconstruct a 45.5-mile stretch of Interstate 90/39 from Madison to the Illinois state line, including the addition of a third lane in each direction and modification of interchanges.

"It's—in general terms—time to upgrade," said DOT project manager Larry Barta. "Traffic on that stretch has steadily increased where four lanes won't be handling it for much longer."

Traffic is expected to continue increasing over the next 20 years, particularly as Illinois expands its toll way to six lanes, he said.

The cost of the project is estimated at $715 million. Barta said funding for major projects is "pretty well spoken for" through 2015. But as soon as funding is available, the project will be constructed in segments over about five years, he said.

Barta said the DOT plans to divert traffic across the median so four lanes of traffic can safely operate on one side of the Interstate while the other side is being reconstructed.

Planned improvements include:

Janesville area

-- Highway 11 bypass/Avalon Road: Interchange ramps will be adjusted to give motorists enough distance to accelerate and decelerate.

-- Highway 11/Racine Street: The interchange will be reconstructed, and signals will be installed on the ramps.

-- Highway 14/Highway 26: The existing interchanges will be reconstructed. A new four-lane underpass will be constructed to connect Pontiac Drive and Deerfield Drive. Noise wall barriers will be constructed between Highways 14 and 11.

Janesville to Madison

-- Highway 59: The interchange will be reconstructed. A park-and-ride lot also is planned.

-- Highway 51/Highway 73: The interchange will be reconstructed. Highways 51 and 73 will be reconstructed as four-lane divided roadways in the interchange area.

-- Highway 51: The interchange will be updated.

-- County N: The interchange will be maintained, and County N will be reconstructed as a four-lane divided roadway in the interchange area.

-- Highway 12/18 (Madison beltline): The interchange will be reconfigured.

Beloit area

-- Interstate 43: The cloverleaf interchange will be reconstructed.

-- County S/Shopiere Road: The interchange will be reconstructed, and County S will be expanded to a four-lane divided roadway in the interchange area.
