Abstract: The Little Rock Reach is a comparatively straight and relatively narrow reach of the Arkansas River located between Little Rock and North Little Rock, Ark. Six bridges are located in this reach of the river within a distance of about 1.4 miles in the vicinity of mile 165. The model investigation was primarily concerned with navigation conditions in the reach particularly as affected by the bridges and with the development of plans as required to provide satisfactory navigation for both upbound and downbound traffic. An undistorted, fixed-bed , 1:100-scale model reproduced about 3 miles of the Arkansas River and adjacent overbank areas and the six bridges located in the reach. The results of the investigation indicated that with existing conditions navigation conditions would tend to be hazardous because of the limited clearances available at all of the bridges, relative alignment of the bridge spans, limited maneuver distance between bridges, and alignment and velocity of currents. Improvement of the reach would require modification of at least five of the existing bridges and the use of training structures to improve the alignment of currents and to reduce the tendency for shoaling downstream of the bridges.
