Repairs to the John T. Myers Pedestrian Bridge are expected to cost around $2.6-million.
Lafayette is responsible for roughly $524,000. Federal funds will pay for the rest.
Work will include rebuilding the bridge deck, replacing the elevators, and installing a handicap-accessible ramp.
But officials say construction is at least a year away because of the environmental and safety permits the city must obtain.
They say the pedestrian bridge is not a safety concern as of now, but could become one depending on how long the rehab takes.
