PEORIA — Bridge work in Peoria and Creve Coeur highlights a slew of upcoming area road projects.

If weather cooperates, the central Illinois road construction season usually begins around April 1. About that time, work lasting two construction seasons should begin on the Shade Lohmann Bridge carrying Interstate 474 over the Illinois River, said Brian Williamsen, District 4 spokesman for the Illinois Department of Transportation.

The $13.5 million project will include steel repairs and electrical work. Sediment will be removed, and the bridge will be painted.

Work is not expected to end until November 2018, and motorists should prepare for lane shifts and two-way traffic on one side of the bridge, Williamsen said.

“Traffic will be reduced to one lane each way on the eastbound side this year,” he noted in a summary of the project.

IDOT also is resuming work this spring on the Cedar Street Bridge, which carries Illinois Routes 116 and 8 over the Illinois River. Complete structural repairs began last year on the bridge, which is more than 80 years old.

Motorists, however, are expected to face less inconvenience than they did last year. Most of the work, including painting and concrete sealing of the piers, will be under the bridge, and lane closures should be minimal, Williamsen said.

That project is expected to wrap up in early June, Williamsen added.

Williamsen also noted IDOT already has started a project on Illinois Route 116 from Carole Street in Hanna City east to Greengold Road, a stretch of about 1.5 miles. Plans call for the addition of a center turn lane and driveway and culvert improvements, as well as resurfacing. Work will continue until mid-November.

“Minimal traffic impacts are expected until early to mid-April,” IDOT said. “At that time, motorists will encounter lane closures and flaggers controlling traffic.”

Farther west, IDOT plans resurfacing work on Interstate 74 into Knox County. The nearly $12.4 million project on Interstate 74 will extend from the Spoon River to east of Illinois Route 78. Motorists should prepare for traffic to be one lane in each direction. Williamsen said the project should be completed in late November.

At the Peoria County Highway Department, the major road projects this year are replacement of two rural bridges: the Trivoli Road Bridge in southern Peoria County and the Lancaster Road Bridge in Mapleton.

Trivoli Road is closed between Glasford-Canton Road and Todd School Road, and the $1.2 million construction project is to be finished in October.

The $2.8 million Lancaster Road Bridge is expected to be ready in November, although some striping and landscaping on the latter project might not be finished until next spring.

This month the city of Peoria’s Public Works Department resumed work on two Sheridan Road projects.

Sheridan was closed at the creek at Richmond Avenue to complete replacement of the Sheridan Road bridge there. Work is expected to continue throughout the summer.

In addition, the Sheridan Road Improvement project is picking up at Brons Avenue and continuing to McClure Avenue. Improvements will include a bi-directional center turn lane, bike paths, sidewalks and new lighting and should be done by the end of June.

August is the projected starting date for a three-year, $12 million project on Northmoor Road that, when completed, will extend from University Street to Allen Road. At a public meeting last week, Peoria Public Works Director Scott Reeise said construction will start this year on a frontage road between Northmoor Road and Richwoods High School, as well as improvements to the intersection at Rosemead Drive and Northmoor Road, designed to be the new entrance to Exposition Gardens.

In late May or early June the city will start construction on a roundabout at Radnor and Alta roads The $2.5 million project “has been in the works for a number of years” and should be done around Thanksgiving, Reeise said.

Late May is the projected starting time for a project on Folkers Avenue right in front of Trewyn Middle School, Reeise said. The $1.5 reconstruction project, between Latrobe and Freemont streets, will include new sewers and sidewalks, and the goal is to finish before school starts, Reeise said.

On Harvard Avenue, residents should see a substantial project begin in mid or late May between Lake Avenue and Purdue Street, Reeise said.

“We’ve had a couple of public meetings. People are excited to have their road reconstructed, that’s for sure,” Reeise said.

He added, “There will be a sidewalk on one side, a multi-use path on the other, and a complete new roadway.”

This is a two-year project. This year’s part will cost about $2.5 million and should be completed by Thanksgiving, Reeise said.

When work resumes on Harvard next year, crews will go from Purdue to War Memorial Drive. That is expected to cost about $2 million, Reeise said.

During construction this year, Harvard will be open to local traffic only and will remain open in one direction, Reeise said.

“Nobody likes to be inconvenienced during construction season,” he said, “but when the roads are in bad shape, that’s what you got to do.”
