The City of Moorhead completed the road reconstruction of 20th Street South from Sixth Avenue South to 12th Avenue South in 2012. The arterial road reconstruction project, which was funded in large part with federal transportation funds, also included reconstruction of a bike path that runs parallel to the street.

Road Reconstruction Project Description

The newly reconstructed concrete road replaced a deteriorating bituminous pavement, originally laid in 1964. The street had received two bituminous overlays, the first in 1980 and the second in 1989. Assistant City Engineer Tom Trowbridge said the city’s decision to use concrete dates back to 2002 when it began reconstructing other segments of 20th Street. The road’s traffic volume exceeds 10,000 vehicles per day and carries heavy truck traffic; US Highway 10 is to the north and I-94 is to the south. The city wanted a surface that wouldn’t rut and one that required less maintenance.

“Concrete requires less attention over time and will last longer,” Trowbridge said. The bike path also was reconstructed with concrete to minimize maintenance and the need to seal coat.

Project Engineer Josh Olson of Apex Engineering Group, said the road is designed for future expansion. The roadway is constructed to handle four lanes of traffic. It’s now striped for one northbound lane of traffic and one southbound lane with a center turning lane.

To ensure that the road reconstruction was completed over the summer, Trowbridge said the city closed the road to all traffic for the duration of the project. To accommodate residents of an apartment complex that only had access from 20th Street South, the city provided temporary access off a nearby street, constructing a temporary driveway through the city park abutting the project.

The project’s total cost was about $1.2 million. Nearly $990,000, was paid with federal funds administered through the Minnesota Department of Transportation (MnDOT). Property owners, including the city, were assessed $195,000. The remaining balance was funded by the city through bonding.
