LOCATION OF PROJECT

This project is located along IL 17 approximately 2.3 miles east of Interstate 74 (I-74) in Woodhull, Illinois in Henry County. The culvert replacements included in this contract are along IL 17 between County Highway 30 and E. 780th Street. This project is in IDOT Region 2 District 2.

DESCRIPTION OF PROJECT

This project includes the removal and replacement of two existing drainage structures, SN 037- 1183 and SN 037-1015, located under IL 17. The existing structures will be replaced with one 48-inch reinforced concrete pipe (RCP) culvert and one 12’ x 8’ precast concrete box culvert, respectively. Additionally, two existing pipe culverts will be removed, with one pipe culvert replaced with two equivalent round-size 24-inch RCP culverts and drop box while the other will not be replaced. Pavement patching will be performed at all locations where drainage structures are removed and/or replaced. New roadside ditches will be constructed and graded to accommodate the proposed drainage improvements. Roadway improvements consist of milling and resurfacing, construction of new aggregate shoulders, and improvements to entrances connecting to IL 17.

MAXIMUM DROP-OFFS BETWEEN ADJACENT LANES

(Effective April 21, 2023)

When the Contractor’s operations cause a difference in elevation greater than 1.5 in. (38 mm) for a vertical milled face or 2 in. (50 mm) for a lift of HMA resurfacing between adjacent lanes, the lane shall remain closed. The Contractor shall adjust his milling and paving operations so that all traffic lanes are open at the end of each work day.

To meet the above requirement, the Contractor shall:

Place the binder lift immediately following the milling operation before opening the lane to traffic or

Place a temporary wedge after the milling operations (minimum 1V:3H slope) or

Mill a sloped wedge between lanes (minimum 1V:3H slope).

When the difference in elevation between adjacent open traffic lanes is greater than 1 in. (25 mm) and less than or equal to 1.5 in. (38 mm) for a vertical milled face or 2 in. (50 mm) for an HMA lift, “UNEVEN LANES” signs (W8-11(FO)) shall be erected at 1-mile (1.6 km) intervals.

The above requirements were developed based on IDOT Safety Engineering Policy Memorandum 4-21. Any changes to the proposed lift thicknesses, milling depths, or sequence of operations that change drop-offs at the centerline or edge of pavement must follow this policy and be approved by the Engineer.

This work will not be paid for separately but shall be included in the cost of the applicable HMA surface removal pay items.
