Stage 1B is on the east end of the project, at approximately MP 45–46.5, and includes the Quartz Creek intersection as well as the intersection of the existing and proposed Sterling Highway (approximately MP 47). Stage 1B includes realignment of the highway and connection to the old Sterling Highway. Construction will include excavation, rock blasting, a pedestrian undercrossing (Coyote Notch), retaining walls, drainage, guardrail, pavement, and signage and striping. Excess material will be transported to Stage 3. 

 Clearing activities began October 15th on the Stage 1B corridor from MP 45 to 48.  Work for the Fall 2025 season is expected to wrap up by the first week of November.
