Anoka County CSAH 14 Reconstruction

Anoka County, Minnesota

The CSAH 14 corridor traverses the Rice Creek Chain of Lakes parkland and commercial areas, including downtown Centerville and residential areas. It serves as an important east-west connection between Lino Lakes, Centerville, Hugo and other area communities.

Anoka County has begun reconstructing CSAH 14 from I-35W to I-35E. SRF has supported the County throughout this process, beginning with alternatives development, preliminary design, and environmental documentation and moving through final design.

Instead of simply building four lanes, we carefully evaluated traffic levels and designed a combination of two-, three-, and four-lane divided segments to reduce impacts to cultural resources, parks, wetlands, the Rice Creek Chain of Lakes, and downtown Centerville.

To avoid the extensive excavation of peat along a segment in a regional park, 200,000 cubic yards of shredded tires will be used to widen and support the new roadway. In addition, as CSAH 14 continues between Peltier and Centerville Lakes, reduced shoulder widths and cast-in-place retaining walls will minimize the roadway footprint. A trail for pedestrians and bicyclists also runs the length of the corridor.

SRF is currently working with the County on the preliminary design of the I-35E/CSAH 14 interchange.
