Project End Result

The Alaska Department of Transportation, in cooperation with Mass Excavation, Inc., is working to replace the bridges at 20 Mile River, Portage Creek #1, Portage Creek #2, Placer River, and Placer River Overflow, as well as realign sections of roadway within the Portage Curve to improve safety within the corridor. The pathway project will create segments of multi-modal pathway between MP 75, near Ingram Creek, and MP 82, near 20 Mile River. The pathway will include pedestrian under crossings at Placer River, Portage Glacier Highway, Portage Creek #2 and 20 Mile River. Crews will also work on installing grading, drainage, paving, illumination, signage and striping improvements.
