LTRA, working for the TxDOT Amarillo District, performed a control survey for a 2-mi segment of IH 40 in Amarillo and a 2-mi segment of Loop 335 in Amarillo.  The team set survey control monuments every 1,000 ft utilizing multiple GPS observations and digital level loops to establish the horizontal and vertical values.  LTRA prepared survey control data sheets for all established points.  LTRA also performed property research on both segments, plotted deeds and plats, and prepared existing right of way maps for each highway.  In addition, LTRA prepared legal descriptions and parcel exhibits for two acquisition parcels along the Loop 335 for a proposed turn lane project.
