About this file
This is a technical specification document from the Michigan Department of Transportation (MDOT) dated May 2021, illustrating standard traffic control procedures for shoulder work on divided roadways and freeways during short-duration mobile maintenance operations. The document, titled "Shoulder Closure 4402-M-FW-SHL," provides detailed guidance on maintaining traffic flow while work is conducted on roadway shoulders. The specification includes requirements for signing, such as W20-1 "Road Work Ahead" signs, lighted arrow panels in caution mode, rotating beacons, mounted attenuators, and shadow vehicles with optional truck traffic configurations. The diagram designates work area spacing as variable and includes provisions for an appropriately marked vehicle to indicate to the public that maintenance work is being performed in the area. Standard notes reference general maintenance and surveillance (MS2, MS3, MS4) requirements and signing standards (S1, G1, G2, G3, G4) as detailed in MDOT document 102-GEN-NOTES.
No specific pricing terms, contract duration, bid due dates, or award information is contained within this technical specification document. The file serves solely as a standard operating procedure and design reference for MDOT personnel and contractors performing shoulder maintenance work on Michigan's divided roadways and freeways, ensuring consistent application of traffic control measures across the state's transportation maintenance operations.
