About this file
This is a Temporary Traffic Control Guidance attachment that establishes requirements for traffic management during construction activities along the I-90 corridor in Washington State. All temporary traffic control must conform to Section 1-10 of the 2014 State Standard Specifications for Road, Bridge, and Municipal Construction, and all flaggers must possess current flagging cards issued by Washington, Oregon, Montana, or Idaho. Traffic control operations shall comply with the WSDOT Manual on Uniform Traffic Control Devices (MUTCD).
The document specifies detailed restrictions on lane and shoulder closures, permitting short-duration shoulder stops using light vehicles with warning flashers without lane closure, while low-volume access (1 vehicle per hour) requires temporary single lane closure. Single lane and ramp closures are restricted to specific nighttime and weekend hours: Monday through Friday from 8:00 pm to 9:00 am, Friday 10:00 pm through Saturday 7:00 am, and Saturday 9:00 pm through Sunday 9:00 am, with directional variations on Sunday. All closures on Exit 54 Gore Area require ramp closure with pre-approval from WSDOT and the Contracting Officer Representative (COR). Holiday restrictions prohibit all lane and shoulder closures during extended periods surrounding Memorial Day, Labor Day, and the 4th of July, with varying blackout windows depending on the day of the week the holiday falls. All exceptions to these closure hours must receive pre-approval from both WSDOT and the COR, with authority reserved for the State to adjust hours if traffic impacts are determined to be adverse.

3. WSDOT Temporary Traffic Control Guidance
Temporary Traffic Control shall conform to Section 1 – 10 of the 2014 State Standard Specifications for Road, Bridge, and Municipal Construction (http://www.wsdot.wa.gov/publications/manuals/fulltext/M41-10/SS2014.pdf).
All flaggers shall possess a current flagging card issued by the State of Washington, Oregon, Montana, or Idaho. The flagging card shall be immediately available and shown to the Government CO or COR upon request.
Traffic control shall conform to the WSDOT Manual on Uniform Traffic Control Devices (MUTCD) and the following general guidelines:
| •Short-duration shoulder stops in the work zone utilizing light vehicles properly equipped with warning flashers will be allowed without a lane closure. |
| •Low-volume access (<1 vehicle per hour) to and from the highway will not normally require a lane closure. Large and/or slow-accelerating trucks will require a flagger(s) and temporary land closure. |
| •Vehicles and/or equipment may be left overnight behind permanent traffic barrier or outside the Clear Zone. For this project, the clear zone extends to 30 feet from the traveled way (fog line). |
| •During times when multiple vehicles are entering or exiting a site from the highway shoulder or median (>1 vehicle per hour), a temporary single lane closure will be necessary. |
