The South Dakota Transportation Commission approved six projects for various state highways and agreed to replace a Yankton bridge Thursday.
The commission decided to proceed with the Pine Street crossing on Marne Creek, after hearing Yankton city officials would pay the amount exceeding the original state grant.
The commission had agreed April 28, 2016, to give Yankton $854,904.60.
A department engineer later estimated the project would cost $1,373,810.20. But the lowest bid of four received came from Swingen Construction Co. of Grand Forks, N.D., at $1,709,466.10.
State Department of Transportation official Sam Weisgram assured the commission Yankton would cover the remainder.
Weisgram said the proposed bridge has some unusual architectural features. “We don’t have a lot of experience with some of the items here,” he said.
The commission approved several road projects:
A 24-mile stretch of US 14 will be resurfaced between Hayes and Fort Pierre in Stanley County. A bridge deck also will be resealed over Willow Creek about eight miles west of US 83.
Anderson Western Inc. of Bismarck, N.D., submitted the low bid of $4,733,122.26. Five companies bid. Estimated cost was $4,710, 823.06.
