Link. The opening sentence of the item resolves things:
A deficient bridge on Viking Boulevard will be replaced under a contract awarded by the Anoka County Board Oct. 10.
Redstone Construction, LLC submitted the lowest of seven bids, totaling about $5.5 million, to construct the new bridge on Viking Boulevard over the Rum River in Oak Grove.
So "deficient" modifies "bridge" and not "bridge replacement contract."
That makes the board look better.
