Road Construction Projects
Linn County works to minimize the disruption caused by road construction, and in so doing, wants to keep the public aware of construction projects, timelines, and traffic impacts. Construction projects often mean traffic delays and disruption, but they also mean improved infrastructure and improved traffic flow.

The roads scheduled for concrete overlays will be closed to all traffic during paving. Local traffic will be allowed on the concrete pavement as soon as joints are sealed and maturity is reached (typically within 40 hours). The contractor is required to allow local access as soon as possible. All residents adjacent to the concrete paving are encouraged to plan travel accordingly during construction. There will be times when access is not possible for local traffic. If this is a concern, parking your vehicle at the nearest point of relief and walking to your home will be required.
A typical grading project involves replacing or extending crossroad and entrance culverts, cleaning ditches to improve drainage, curing snow trap areas, removing obstructions (trees, landscaping, headwalls) within the right of way, flattening slopes, etc. Traffic count determines the amount and type of rock placed on the road. Gravel roads with a traffic count over 150 vehicles per day (VPD) will generally receive a 3-inch macadam stone (1-3-inch sized rock) base with a 3-inch choke stone (three fourths inch plus sized rock) surface layer.
