Traffic Signs

The Manual on Uniform Traffic Control Devices for Streets and Highways (MUTCD) has been adopted as the standard for all Regulatory and Warning signs used on Corps of Engineers project roadways for vehicular traffic. Many states also have a supplement to the MUTCD, which lists additional approved signs. The National MUTCD is available on-line at the links below. Three important traffic-related sign types in the Corps sign standards vary from the MUTCD. These include: Approach and Roadway Directional signs (see EP 310-1-6a, Section 6), Recreation Symbol signs (see Section 8), and Parking and No Parking signs (see Section 9).
