The 19-mile FM 116 corridor between north Copperas Cove and US 84, near Gatesville, carries considerable commuter traffic, particularly to and from the nearby Fort Hood. To improve safety and operations on the route, the Texas Department of Transportation (TxDOT) converted the corridor from a two-lane rural section to a Super 2 which includes two travel lanes with a central alternating passing lane.

Lochner was selected to conduct a study to determine the limits of each passing zone. Following the study, Lochner proceeded with design which, in addition to the third lane, included an asphalt pavement overlay for the entire project length, the widening of the existing 6-foot shoulders to 10 feet, and the replacement of a 485-foot-long prestressed concrete girder bridge under phased construction. This stretch of FM 116 includes 62 cross drainage structures, 164 driveways, and 21 cross streets, all of which were accommodated in the final design. Many of the drainage structures required extension or replacement. Lochner completed the design under an expedited schedule of just nine months and contained all roadway widening within the existing right of way.

Lochner also provided construction support services for the project, reviewing shop drawings and responding to Contractor requests for information.
