Since 1999 more than 400 collisions have been recorded at bridges throughout the South Split (intersection of I-65/I-70) in Indianapolis, Indiana. On February 22nd, 2013 a semi-trailer hauling elevator equip-ment collided with the Virginia Street Bridge overpass, causing a sup-port beam to split, and severely impacting traffic. INDOT responded swiftly engaging with Continental Mapping to complete a mobile lidar aerial and mapping project for the site. Time was of the essence to provide survey data to INDOT’s engineers for design modifications.

With under a week’s notice, Continental Mapping mobilized its VMX-250 Riegl mobile lidar system and plane to collect mobile lidar

and aerial imagery. The mobile unit collected over 15 lane miles of highway including over 30 bridges. Continental Mapping fused the

mobile lidar and imagery to complete 1”=25’ planimetric mapping throughout the corridor and deliver stereo bridge clearances, 1’ con-tours, DTM, orthos and a calibrated point cloud all to within 0.1’ verti-cal accuracy on hard surfaces.
