Secret’s out – construction along I-5 over Secret Creek near Stanwood is coming soon.
Over the next two years, we’ll remove the smaller, aging culverts (fish passage barriers) under both directions of I-5 and Old Highway 99 and install three new fish-approved bridge structures to enable safe fish and wildlife passage under the freeway and highway.
During construction, northbound and southbound I-5 will both shift over to a two-lane, temporary bypass along the mainline until the end of December 2025. This will bring I-5 in each direction from three lanes, down to two and decrease the speed limit in the area from 70 mph to 60 mph. In 2026, construction will switch over to Old Highway 99, which will be closed for part of the year and a detour will be in place.
