The Texas State Department of Highways and Public Transportation (SDHPT), Highway Design Division, in cooperation with the Office of the State Governor, The Office of the State Historic Preservation Officer, and the City of Laredo, has recently investigated the approach roadway and the bridge site of the proposed Colombia-Laredo International Bridge across the Rio Grande, in Webb County, Texas. The work was conducted to identify cultural resources in these areas and to offer a preliminary description and evaluation of historic properties considered to be potentially eligible to the National Register of Historic Places.

One historical archaeological locale, 41WB205 (portions of the early 20th century mining community of Darwin) and one prehistoric terrace occupation zone, 41WB206, were investigated. Although the portion of 41WB205 within the projected roadway has been severely impacted by modern alteration, the larger and less disturbed surrounding site area is considered to be potentially eligible for the National Register.
