a Location of the North Branch Park River watershed in Connecticut, USA. b Location of the four sampling sites. Sites A and B were located upstream of the construction site, and sites C and D were downstream of the construction site. Stream crossing I is a concrete single-span road bridge, stream crossing II is a pedestrian truss bridge, and stream crossing III is the new concrete single-span road bridge. The dashed line represents a stream channel that only conducts water during high flow; only the northern channel conducts water during normal flow. c Satellite view of the previous structure (embankment with culverts) in March 2012 (top) and the new structure (bridge) after it was completed in February 2013 (bottom)
