SPT has cut over 150,000 miles of shoulder and centerline rumble strips throughout the United States. Ever since rumble strip mills started cutting 15-30 miles of roadway in a single 8-hour day, highway authorities have specified a moving operation lane closure for shoulder rumble strip construction.

Below are a variety of maintenance and protection of traffic drawings for shoulder and centerline rumble strip construction:
- Slow-moving operation for shoulder rumble strips on a multi-lane highway
- Slow-moving operation for shoulder rumble strips at an exit ramp on a multi-lane highway
- Slow-moving operation for shoulder rumble strips on a two-lane, two-way secondary road
- Flagging operation for centerline rumble strips on a 2-lane, 2-way secondary road
- Flagging operation for in-edgeline or shoulder rumble strips on a 2-lane, 2-way secondary road
Surface Preparation Technologies, LLC has safely used the previous traffic control plans and others to construct rumble strips on various U.S. roadways. Although these plans are based on M.U.T.C.D. standards they are only being provided as examples. The use of these plans or any portion thereof must be reviewed and approved for use by local traffic engineers.
