(AP) — Repairing the faulty pedestrian bridge near Lincoln’s new arena is becoming costly.

Investigating the failure of two of the bridge’s girders will now cost at least $84,000. The group overseeing construction of the Pinnacle Bank Arena approved a new contract with an engineering firm on Friday.

Whoever is responsible for the bridge problems will be expected to pay the repair bills.

The faulty girders in the $7.9 million bridge are expected to be replaced soon. Officials expect that roughly 5,000 people will use the bridge to cross from the arena to parking.

Lincoln Police say an intoxicated 22-year-old man fell off the bridge Sunday morning. His injuries were not life threatening, and he was ticketed for trespassing.
