The Cedar Valley Nature trail will be closed between Shultz Road and Center Point for paving starting August 8th.   The original plan was to start paving on July 18th, but the contractor has opted for a later start.

Here is the press release from Linn County Conservation:
LINN COUNTY, IA –August 4, 2016- The Cedar Valley Nature Trail will be closed to the public from Schultz Road north to Iowa Street in Center Point starting Monday, August 8th for construction of the Cedar Valley Nature Trail Phase 4 Paving Project. The contractor, Vieth Construction, will be preparing the site to replace the crushed limestone surface with asphalt pavement. Re-opening of this section is scheduled for mid-November as weather and ground conditions permit. A concrete surface will be applied on the trail from Iowa Street through Center Point to the Grubbs Creek Bridge near Ash Lane later this fall if time allows, or in the early spring. Linn County Conservation appreciates the public’s patience during this 3.5-mile trail improvement effort.

Next year, there may be some maintenance that may close that portion of the trail for a week or so while they attend to some work in the ditches, etc.
Also the concrete/hard surface portion from Iowa Street through Center Point to the Grubbs creek bridge will take place next spring when the weather allows
