The Regional Transportation Authority Board voted last week to move forward on a plan to build the bridge and two other wildlife crossings, tunnels that would sit beneath Oracle Road. The estimated cost for the structures tops more than $8 million, to be paid with money allocated from the RTA roadway improvement plan.
