Bridge Surveys

Our team surveyed 49 bridges by preforming cross sections of the creek/river 5′-10′ upstream from the bridge, both sides of the bride, and any abutments, a row of shots across the deck of the bridge, a shot on top of the guardrail, a cross section of the creek/river 5′-10′ downstream from the bridge and a sketch of the bridge.

Additionally, our field crew set 20 aerial targets along 4 stretches of creek/river.
