Acrow Bridge Completes Two Projects in South Dakota; State Adds to Existing Modular Bridge Inventory

Reusable Steel Systems Help Minimize Long Detours in Rural Areas

PARSIPPANY, NJ--(Marketwired - Feb 16, 2016) - Acrow Bridge, a leading international bridge engineering and supply company, announced the recent completion of two jobs in South Dakota. One of the projects used Acrow components currently owned by the South Dakota Department of Transportation, the other structure was built from newly purchased components, which adds to the state's growing inventory of Acrow modular steel products for use in emergencies and planned detour projects.

When a planned detour on State Route 281 over the Maple River near Frederick was needed, SDDOT purchased an Acrow 160' long by 30' wide TDR3 for the job and other bridge projects identified in their forecasts. In addition to being a longer structure than those already owned by the state, this newer bridge is AASHTO HL-93 load rated with new bridge-rail capability meeting the TL 3 or 4 type specifications and has an epoxy-aggregate coated decking. The project began in May 2015 with design engineering by SDDOT and Acrow. The contractor was Duininck, Inc. The structure was installed with a crane assisted method, and was removed with a full cantilever launch, accomplished in a very tight work area. The temporary structure provided full traffic flow along this major artery in a rural area where detour routes are prohibitively long.

For another temporary structure on I-29 in north Sioux Falls, SDDOT used a 140' long by 30' wide Acrow 700XS bridge it has owned for more than a decade, and has used over the years in several projects. While the decking was originally covered with asphalt, several years ago the state applied an epoxy-aggregate non-skid coating, upon receipt of information supplied from Acrow. This new coating matches the finish on the newly purchased 160' bridge and provides a drivable surface as soon as the decks are installed. SDDOT and Acrow were joint design engineers and the contractor was The Journey Group (formerly Sioux Falls Construction). The installation was successfully completed using a two-crane pass with midair connection.

"South Dakota DOT has owned Acrow bridging for several years," said Tom Pinder, Western Sales Manager at Acrow. "As per RFQ stipulations, contractors are required to contact us for on-site assistance and installation procedures that are tailor-fit to the location needs and contractor's capabilities. When the bridge is removed, Acrow is there again to assist in the process and do a final inventory back at the storage yard."

"The modular design of Acrow bridges provide a good solution for state DOTs needing cost-effective and rapid temporary bridging solutions," said Bill Killeen, President and CEO of Acrow Bridge. "Our customizable components can be engineered for many different applications, have an estimated life span of 75-100 years and are virtually maintenance-free."
