Traffic Control Needs on State Trunk Highways

The Traffic Engineering Section of the Minnesota Highway Department undertook a three-fold study to determine (1) the extent of nonconformity with the new standards of the existing traffic control devices on the trunk highway system, (2) the estimated cost to bring all devices into conformity with the new standards, and (3) a program or schedule for modernization to achieve complete compliance with the new standards by the end of 1966.
