Project Details
The purpose of the I-17 Flex Lane project is to mitigate peak time congestion issues along a 23-mile segment of the I-17 corridor between Metropolitan Phoenix and northern Arizona. The project will increase mainline roadway capacity, improve safety, and to reduce the potential for significant delays. Being delivered as a design-build-operate-maintain (DBOM), Public-Private Partnership (P3) project with a cost of over $500 million, the improvements consist of the following:
- Widening the roadway to achieve three general purpose lanes in each direction.
- Adding two “Flex Lanes” that will carry either northbound or southbound traffic, depending on directional demand.
- Modifications to existing bridges, drainage structures, and ramps to accommodate widening.
- Multiple utility relocations throughout.
- Intelligent Transportation System (ITS) technology for central monitoring and lane management.
