Snohomish County Public Works will be performing road construction north of Arlington which will require a limited number of motor vehicles to co-exist with Centennial Trail users. Controlled vehicle traffic will occur Monday-Thursday, 7:30 am - 4:00 pm, beginning 6/16/14 and ending 6/27/14. Vehicles will use about 1000 feet of trail, entering/exiting where it intersects Lake Armstrong Road and Quarry Road. While the trail will remain open for all users, delays can be expected during construction hours.
