Highland Acres Road

Clapsaddle-Garber Associates was retained by Marshall County for the design and reconstruction of Highland Acres Road, which began in 2004 and was completed in 2010.  The 2.4 mile project was split into six phases and included a new alignment and profile to accommodate a three lane asphalt roadway with a 45 mph design speed, three bridges, and an overpass of the Union Pacific Railroad to eliminate an at-grade crossing.  The project required extensive dirt work with 30' of fill required on the north abutment of the Union Pacific overpass and 15' of fill to improve the intersection of Highland Acres Road and Lincoln Way on the west edge of Marshalltown.  CGA's responsibilities included topographic survey, soil boring coordination, roadway and drainage design, plans and specifications, ROW and easement negotiation, preparation and filing all Fee Acquisition Plats, estimation of costs for each phase, creating files for contractor to perform stakeless grading, and setting all final ROW monuments.  Land acquisition included 25 parcels with 13 fee acquisitions and one relocation assistance parcel.  Total cost of the project was approximately $8.2 million.

Coordination was key to the project.  CGA lead the design team, including the bridge and soils engineers, in coordinating with Marshall County, the City of Marshalltown, the Union Pacific Railroad, Alliant Energy, Marshalltown Water Works, and the property owners along the corridor.
