Linn Creek/ Highway 30 Trail

CGA provided planning, survey, and design services to the Marshall County Conservation Board for the Linn Creek/Highway 30 Trail Expansion/Connection in Marshall County.  Project planning began in 2005 with route investigations including meeting with property owners in the area as well as the Iowa DOT in order to connect the existing Linn Creek Trail system to the Existing Highway 30/330 Trail system.  CGA prepared multiple route alternates and estimated costs for the owner's consideration which led to the final trail alignment.

Design began on the trail in the fall of 2009.  CGA worked closely with the Marshall County Conservation Board, Marshall County Engineer's office, and Iowa DOT to finalize the design and construction documents for the 10' wide PCC trail.  The alignment begins at the intersection of Marsh Avenue and the Highway 30/330 trail on the south side of Highway 30.  Pedestrian lanes and barriers were added to the existing bridge over Highway 30 and the trail continued east within the Highway 30 Right of Way.  At the intersection of Business 30 and Highland Acres Road, the alignment turns to run north on the old Highland Acres Road alignment in order to utilize existing drainage structures, subbase, and bridges before it ties into the Linn Creek Trail system at Grimes Farm in Marshall County.
