TRAFFIC CONTROL PLAN

Effective 1985 Revised 4/17/23

During the entire construction period, the road shall be kept open to traffic as follows:

(a) The highway shall be kept open to at least one lane of traffic at all times and to two lanes of traffic to the greatest extent possible, except for as stated within these special provisions.

(b) Access to all public roads and private entrances shall be maintained during all stages of the work.

(c) The road shall be kept open on the detour road during construction of the proposed structure, grade change, or relocation.

(d) The road shall be kept open over one lane of the existing or new bridge during construction of the opposite lane of the structure.

Prior to allowing traffic on any portion of the roadway that has been cold milled, the Contractor shall have erected "Rough Grooved Surface" and "Uneven Pavement" signs that conform to the details shown in the plans. A minimum of one sign at each end of the improvement will be required. The Contractor shall maintain the "Rough Grooved Surface" signs until the cold milled

Section (41-8,1,2) RS-5; 1B-1 surface is covered with binder. The Contractor shall maintain the "Uneven Pavement" signs until the resurfacing operations are completed. The cost of furnishing, erecting, maintaining, and removing the required signs shall be included in the cost of the contract.

The temporary rumble strips shown on the Traffic Control Detail in the plans will be required on this project.

At all locations where the Contractor's equipment is required to cross the traffic lanes, traffic control and protection in accordance with Standard 701306 shall be used. The "One Lane Road Ahead" signs indicated on this standard shall be replaced with "Road Machinery Ahead" signs [W21-3(0)-48]. The cost of furnishing, erecting, maintaining, and removing the required signs shall be included in the cost of the contract.

NOTIFICATION PRIOR TO STARTING WORK

Effective 12/05 Revised 2/10/17

Revise the first sentence of Article 107.09 Public Convenience and Safety to the following: “The Contractor shall notify the Engineer at least 14 days in advance of starting any construction work.

For projects involving width or height restrictions or complete closures of the roadway or ramp, an additional seven days of notice (21 days total) will be required.”

This additional notification is required, so the public can be notified of the pending construction.

CHANGEABLE MESSAGE SIGNS

Revised 4/15/20

This work consists of furnishing, placing, and maintaining changeable message sign(s) according to Section 701 and the following:

A total of five changeable message signs shall be required in this contract. All signs must be in place and operational for a minimum of 14 calendar days prior to lane or roadway closures. Each sign shall state the day work will begin and delays are possible. The exact message will be approved by the Engineer. The Contractor may be required to relocate each sign multiple times during the contract at his or her expense. The exact location of the placement of these signs shall be determined in the field by the Engineer.

This work will be paid for per CALENDAR DAY for CHANGEABLE MESSAGE SIGN.

DROP-OFF NEAR THE EDGE OF TRAVELED WAY

Revised 2/27/17

In order to be in compliance with Safety Engineering Policy Memorandum 4-15 (Drop Off Policy) the Contractor will utilize Traffic Control and Protection Standard 701326 and night time work zone lighting at any time a greater than 12” drop-off is located within 8 ft. of the edge of the nearest open traffic lane. Additionally, to reduce the time traffic is exposed to a drop-off, nighttime work will be allowed. Night time traffic control shall conform to the requirements for the standard in use and all applicable portions of Article 702.

For drop offs >1.5” but <12” there shall be no long duration stationary operation allowed (14 days or more) located within 8 ft. of the edge of the nearest open traffic lane.

The Contractor will be assessed a traffic control deficiency deduction per Article 105.03(b) for each day a drop off greater than 1.5” exists for more than 14 days within 8 ft. of the edge of the nearest open traffic lane.

COOPERATION BETWEEN CONTRACTORS

Revised 2/10/17

The Contractor is to be aware that traffic control limits of this contract may overlap those of another project(s) that may be under construction along IL 37 concurrently with this work. The Contractor shall coordinate his/her work with the other contractors to minimize any possible conflicts.

MOWING

Effective 12/11/01 Revised 7/17/17

This work shall consist of mowing the roadway foreslopes to the ditchline or for a width of 15’ from both edges of pavement or paved shoulder, whichever is less. At intersecting roadways, the mowing shall extend to the proposed right of way for a distance of 300’ on either side of the intersection. The height of the mowing shall not be more that 6’’. Equipment used shall be capable of completely severing all growth at the cutting height and distributing it evenly over the mowed area. The Contractor will not be required to mow continuously wet ditches and drainage ways, slopes greater than 1:2.5 (V:H), or areas which may be designated by the Engineer as not mowable. Mowing shall be done within the project limits during the construction of the project as directed by the Engineer and prior to the final inspection of the project. Any subsequent mowing required to disperse mowed material shall be considered as included in the cost of the mowing. Debris encountered during mowing, which interferes with the mowing operation or is visible from the roadway shall be removed and disposed of according to Article 201.01(a) and 201.10(a).

Section (41-8,1,2) RS-5; 1B-1

Method of Measurement: Mowing will be measured for payment in units of 100’ in horizontal distances along the roadway centerline. For purposes of measurement, the quantity of units to be paid for each individual mowing is defined as the net length of the project as shown on the cover sheet of the construction plans divided by 100’ which includes the left and right sides of the roadway. No allowances will be made for variations in width of mowing.

Basis of Payment: This work will be paid for at the contract unit price per UNIT for MOWING.

AVAILABILITY OF ELECTRONIC FILES

Effective 10/16 Revised 12/11/19

Electronic files of this project will be made available to the Contractor after contract award.

The Contractor shall accept all risk associated with using the electronic files and shall hold the Department harmless for any errors or omissions in the electronic files and the data contained therein. Errors or delays resulting from the use of the electronic files by the Contractor shall not result in an extension of time for any interim or final completion date or shall not be considered cause for additional compensation.

The Contractor shall not use, share, or distribute these electronic files except for the purpose of constructing this contract. Any claims by third parties due to use or errors shall be the sole responsibility of the Contractor. The Contractor shall include this disclaimer with the transfer of these electronic files to any other parties and shall include appropriate language binding them to similar responsibilities.

BORROW EXCAVATION

The submittal shall contain an 8 1/2" x 11" topographic map or sketch containing the dimensions of the area proposed and the locations of pertinent landmarks, the name(s) of the property owner, and the proposed depth of cut. Copies of this map may also be used for subsequent submittal required for the archeological survey of the borrow pit.

The Contractor shall provide access for truck mounted drilling equipment, if required, to and from and in all areas where he/she requests material investigations.

Borrow excavation which is to be used in the roadway embankment without restrictions must have more than 35% of the total sample passing the No. 200 sieve. The soil must have a liquid limit value of 50.0 or less and a plasticity index value of 12.0 or more as defined by the AASHTO Classification System. These soils shall be capable of obtaining the required design embankment strengths. Soils proposed by the Contractor for furnished excavation or borrow which do not meet the aforementioned requirements will be assigned varying degrees of restrictions up to and

Section (41-8,1,2) RS-5; 1B-1 including complete rejection depending on the nature and engineering properties of the material.

These restrictions, if any, will be set forth in the proposed borrow material report.

It is anticipated that, depending upon the workload at the time, this field and laboratory investigation may take up to 15 days.
