Construction Continues on US 412 Bypass

One of the largest projects in Arkansas highway history continues toawrd its Mid-2019 completion date in Benton County. The US 412 Bypass (CA0907 in AHTD parlance), a new terrain, controlled access roadway facility of 4.5 miles was bid December 22, 2014. The low bidder was Eutaw Construction Co. of Aberdeen, MS with a bid of $100 million. Bid tabulation available here.

Construction began on the project in March 2015, including roadway embankment with bridge structures for a four lane divided segment of Hwy. 412 and a full freeway interchange with I-49 just south of the Lowell exit. The project includes 2250 tons of structural steel and over 240,000 tons of concrete.

The US 412 bypass is a part of the long-term plan for a freeway facility to bypass the Northwest Arkansas cities. The ultimate goal is to connect existing freeway segments at US 412 in Tontitown and the Beaver Lake bridge east of Springdale.

CA0907 is part of the Connecting Arkansas Program, a voter approved temporary half-cent sales tax to fund continued construction of four-lane highways to connect all four corners of the state. For more information on CAP, see
