Project Overviewx

HDL provided surveying and mapping services for the Glenn Highway realignment project between MP 84 and 92. This project rehabilitated approximately 7.5 miles of the Glenn Highway to preserve and extend the service life of the highway, enhance safety, and potentially provide passing lanes and climbing lanes

HDL surveyors established horizontal and vertical control for the realignment portion of the project and developed existing ground surface cross-sections for comparison against existing LiDAR data to determine the accuracy of the LiDAR data for design purposes. We also provided survey ties to boreholes from the geotechnical instigation, topographic and bathymetric survey at the proposed Purinton Creek Bridge site, and topographic and hydraulic cross-sections of three stream crossings.
