Let’s get started!
Station 1 - Project Schedule
Project completion scheduled for 2027.
Station 2 - 2022 Construction Updates
We’ve been busy in 2022!
- The Scarsella Bros. focused summer 2022 construction on Phase 1A (MP 56 to MP 58).
- QAP-Traylor Joint Venture, the new Construction Manager/General Contractor (CM/GC), will continue work on the Pioneer Road construction and clearing during the remainder of the 2022 season.
- The CM/GC completed development at Tract C and disposal areas.
Station 3 - West End (Phase 1A)
- Under construction with work on the retaining wall and wildlife crossings.
- Finishing construction in 2023.
- Features: 12-foot lanes and 8-foot shoulders, wildlife crossings, and rock cuts with mesh retaining walls.
Station 4 - East End (Phase 1B)
- Design advanced with the submission of the 99% Plans, Specifications, and Estimates (PS&E) check set plan set.
- Conceptual design of a future connection from Quartz Creek Road to Kenai Peninsula Borough roads in process (MP 44.5).
- Utility agreements are being finalized.
- Right-of-way acquisitions in process.
- Construction timing tied to Phase 3.
Station 5 - Juneau Creek Bridge (Phase 2)
- DOT&PF made a Bridge Type Selection; Concept 12: Steel Plate Girder bridge was chosen.
- The Steel Plate Girder bridge design was advanced to 40%.
- Construction to occur 2023–2026.
Station 6 - New Alignment (Phases 3-6)
Schedule/Timing
- Phase 3 & 4 Early Work Package began construction in August 2022 and is anticipated to be completed in 2024.
- Finished road profile will be completed as part of Phases 1B and 5 from 2024 – 2026.
Overview
- New segment of highway extends from MP 47 to MP 56.
- Includes key elements that help meet project needs: reduce highway congestion, meet current design standards, and improve highway safety:
- Alignment pulls away from Kenai River, provides straighter alignment compared to existing corridor. Straightening alignment offers more passing opportunities.
- New alignment road grade climbs up to Juneau Creek Bridge on either side, providing opportunities for slower vehicles to ascend steep grades in outside climbing lane without slowing traffic.
- Features along new alignment include:
- Pathway (requested by the community) along south side of new highway. Design is in progress.
- Pathway will create pedestrian connections to other trails and allow construction to use excess material on-site instead of hauling it away.
- Wildlife crossings: one overcrossing, two undercrossings, designated crossing corridors on either end under Juneau Creek Bridge, and three oversized drainage culverts.
Station 7 - Recreational Features (Phase 3 – 6)
Juneau Falls Trailhead
- New parking and dedicated left-turn lane
- New trail connecting parking lot to Resurrection Pass trail with separate equestrian access trail
- New Juneau Falls Overlook accessible via 1/4-mile trail from parking lot
- Parking lot to accommodate access road and include snow storage
Bean Creek Trail
- New pullout built to access the trail.
- Trail will have minor realignments due to road construction and access to trail under Juneau Creek Bridge.
Slaughter Ridge
- Hikers will be able to access Slaughter Gulch Trail through highway undercrossing structure sized to include creek crossing.
Station 8 - Western Intersection (Phase 5)
- Land exchange updated; DOT&PF to purchase land from Cook Inlet Region, Inc. (CIRI).
- DOT&PF is working closely with CIRI to permit this summer’s pre-construction activities (geotech, clearing, and H&H fieldwork).
- Overview of Phase 5 Design concept:
- The intersection of the new and old Sterling Highways at the west end (Phase 5) will feature a tight diamond interchange design. This design will provide the best traffic safety and minimize impacts on cultural resources and wetlands.
- Design Next Steps
- Phase 4/5 Early Work Package
