Home / I-81 & I-70 Transportation Systems Management & Operations (TSMO) Plan (2020)
- January 31, 2023
The Interstate 81 and Interstate 70 Transportation Systems Management and Operations (TSMO) Plan complements on-going interstate planning and construction efforts in Washington County. Both I-81 and I-70 are priority freight corridors, experience on-going construction activities and have a history of weather related travel impacts and severe accidents. This plan identifies non-capacity adding strategies to help optimize traffic flow during recurring and non-recurring congestion on existing facilities. As capital funding for capacity expansion of the interstates continues to be pursued, this plan focuses on three different categories of strategies for implementation: (1) geometric and safety improvements, (2) traffic flow and signals and (3) intelligent transportation systems (ITS) expansion.
