FM 973 to be expanded into 4 lane road.

As of May 2017, FM 973 along Austin Bergstrom International Airport is being expanded from 2 lanes into 4 lanes. FM 973 will eventually be expanded into a 4 lane road. Contractors from a handful of construction companies have already began construction along the left side of FM 973 all the way from the intersection of FM 973 & Burleson Road up to the intersection of FM 973 & Pearce Lane. Construction work at the intersection of SH 71 & FM 973 has been completed. Lane expansion on FM 973 is a part of the Highway Improvement Program implemented by the City of Austin.
