Projects on nearly every major regional traffic artery in Metro East are outlined in the Illinois Department of Transportation’s (IDOT) Fiscal Year (FY) 2020-2025 Proposed Highway Improvement Program.

Several potentially landmark projects are key to major economic development projects which could help reshape the region, according to area business and political leaders. Among them: replacement of the Interstate 270 bridge across the Mississippi River, a new U.S. Route 67 bypass near Jerseyville, a new Interstate 255 interchange at Dupo and the new Greenmount Road interchange in O’Fallon.

IDOT acknowledges that many — including extensive projects on Interstate 255 and the Interstate 64 tri-level interchange area in East St. Louis — will mean years of traffic slowdowns and tie-ups.

The I-255 project will entail the phased closing sections of between Collinsville Road to Route 15 for months at a time next year.

The U.S. Department of Transportation will cover 39 percent of the IDOT infrastructure program; with Illinois state funds covering 37 percent; Series A bonds, 21 percent, and local matching funds, 2 percent.

The projects are part of Gov. J.B. Pritzker’s $41.5 billion Rebuild Illinois program. To pay for it, Illinois on July 1 raised the state gasoline tax, from 19 to 38-cents-a-gallon and increased vehicle registration fees.

While 16 percent of funding under the program would go “to strategically expanding the system in areas where data have shown the investment will be highly effective,” the plan will dedicate 75 percent of funding to reconstructing and preserving roadways and bridges, according to an IDOT statement. The remainder targets necessary traffic and safety improvements.

That marks a major shift toward long-term infrastructure preservation, according to the IDOT statement.

A few of the projects (noted below) are to begin in state FY 2020. However, most are scheduled for state fiscal years 2012 through 2025. The road program was announced Oct. 10. The road plan at this point remain technically in the proposal stage and IDOT continues to take public comment on it.

Among major projects planned for IDOT Region 8 (encompassing Greene, Calhoun, Jersey, Madison, Bond, Clinton, St. Clair, Monroe Randolph, Washington, and Marion counties) are:

 Interstate Highways

Interstate 55/64/U.S Route 40/Illinois Route 4 from the Mississippi Rover to the I-64 trilevel interchange in East St. Louis. — Major highway renovation including lighting, bridge joint replacement and repair, bridge deck overlay and bridge repair.

Interstate 64 under Illinois 111 —  Interchange reconstruction, bridge replacement, and ramp repair.

Interstate 64/U.S. Route 50 from just west of Greenmount Road in O’Fallon to 1.1 miles west of Illinois Route 158 — Construction of additional lanes and resurfacing.

Interstate 255/U.S. Route 50 from Illinois Route 3 in Dupo, across Madison and St. Clair Counties, to Collinsville Road. — Highway resurfacing and patching, ramp repair, shoulder repair, and bridge repair or replacement along a 30.2 mile stretch of highway. Scheduled start: 2020

A new interchange on Interstate 255 at Imbs Stations Road and Davis Street Ferry Road in Dupo is scheduled for construction during 2025.

Interstate 270 at the Mississippi River in Madison County —Mississippi River Bridge replacement is to be complemented by approximately 10 miles of additional lanes, road reconstruction, resurfacing, and bridge superstructure work; extending east to Illinois Route 203.

That includes road and bridge expansion and reconstruction across the 2.3-mile Mississippi River bridge approach — extending from the river to the Chair of Rocks Canal.

Then highway expansion and improvement will then continue east to Illinois Route 203; entailing reconstruction of intersections with Illinois Route 3,  Illinois Route 111 and Route 203.

U.S. Highways

U.S. Route 67 at the Delhi Bypass in Jersey County — Construction of 3.2 miles of new four-lane expressway will provide a bypass around the community of Delhi.

The IDOT plan also calls for preliminary work on future widening of U.S. 67, from two to four lanes, north from Jerseyville into Green County as well as south to the Madison County line.

The IDOT program also calls for projects on the Clark Bridge (U.S. 67) and the deck sealing;  intersection reconstruction at Formosa Road-Bethany Road on U.S. Highway 40 ($24 million);and road and bridge work long U.S. Highway 50 at various locations from Silver Creek east through Clinton County, including Kaskaskia River bridge repairs. All are scheduled for 2020.

State Highways

Illinois Route 3 Connector – extending across East St. Louis from Monsanto Drive in Sauget to the River Park Drive Connector – is the centerpiece of maintenance and improvements on the highway extending from it north terminus in Godfrey to its southern terminus in Cairo.

In addition to the new $49 million connector roadway – with its new bridge and a newly-built approach through Sauget – the IDOT plan for Route 3 calls for:

  • Pavement improvement projects in Cahokia and various locations across Monroe and Randolph counties,
  • Reconstruction of the intersection with Pierce Lane in Godfrey,
  • Pavement overlay and patching on the section concurrent with Homer Adams Parkway in Alton,
  • Reconstruction from New Poag Road to Industrial Drive in unincorporated Madison County, and
  • Reconstruction at 20th street in Granite City.
