I-25 Bridges Over Ilex and UPRR Design Build

The first project of Phase 1 of the Preferred Alternative is moving forward into design and construction.  The structurally deficient Ilex Viaduct will be replaced with two separate bridges. The project will maintain full access off Exit 98A to Ilex Street until future phases of construction. Preserving this existing interchange requires removal of the existing Ilex Street. To retain access to the northbound ramps, a portion of the ultimate Stanton Avenue extension is included to connect these ramps to Santa Fe Avenue. A minimal amount of I-25 reconstruction will be required to tie the ultimate bridge location (under the shifted I-25 alignment) back into the current I-25 alignment until subsequent phases of the project are constructed. Improvements to the southbound on-ramp from 1st Street and the northbound off-ramp to 1st Street are also included in this project, along with the viaduct replacement on I-25 between the Ilex Viaduct and the 1st Street Bridge. The Ilex Bridge to 1st Street on I-25 project will be the first project for construction to begin in the summer of 2014.
