About the Viaduct Alternative
The Viaduct Alternative would involve a full reconstruction of I-81 between approximately Colvin Street and Hiawatha Boulevard and a full reconstruction of I-690 between Leavenworth Avenue and Lodi Street.
The existing viaduct would be demolished and replaced by a new viaduct, which would be built to current design standards. Almond Street would be reconstructed and include new pedestrian and bicycle amenities.
The alternative would include a full I-81/I-690 interchange (with connections in all possible directions), interchange modifications, bridge replacements and other features.
The Viaduct Alternative would require the acquisition of 24 buildings. Construction would be anticipated to take six years and cost $2.2 billion.
