I-81 Viaduct Project

Would replace the I-81 viaduct with a new viaduct that meets the latest engineering design standards

Full reconstruction of I-81 between approximately Colvin Street and Hiawatha Boulevard

Reconstruction of I-690 from Leavenworth Avenue to Lodi Street, including all connections between I-81 and I-690

New viaduct would have at least four 12-foot travel lanes (two in each direction) and full shoulders

Cost:

$2.2 billionConstruction duration:

6 years

Note: These visualizations are representative of design intent and the preliminary layout of site elements. These elements will be further refined as the design progresses. The final selection of site elements such as lighting, planting, and paving, as well as materials, colors and finishes, will be determined during final design. Trees and plantings are shown in an established and mature state.

The new viaduct from Harrison

Street would be approximately 10 to 15 feet higher than the existing viaduct

feet tall

South of Harrison Street, the new viaduct generally would be approximately 10 to 20 feet wider, depending on the section, than the 66-foot-wide existing viaduct.

Between Harrison and Genesee Streets, the viaduct would begin to split into separate structures for the northbound and southbound roadways. Multiple structures would carry mainline travel lanes connecting to the local street and interstate network. As a result of these connections, wider shoulders, and other improvements, the footprint of the new viaduct would be substantially wider than the existing viaduct footprint (above in red).
