Opened in 2001, the bridge connects the north and south sides of the Ann and Roy Butler Hike-and-Bike Trail and features an unusual "double curve" design.

[1] The Lamar Boulevard Bridge is one of the main routes across Lady Bird Lake in downtown Austin, but it offers no dedicated bicycle lanes and only narrow sidewalks separated from the street by low curbs.

[3] Instead, in March 1998 the Austin City Council directed the engineering contractor to explore the possibility of building a separate bridge for pedestrian use.

This resulted in two curved avenues crossing each other over the lake, intersecting and overlapping to create a wider space in the middle that could serve as a gathering place and look-off point.

Building on this concept, the architects designed a structure with a double-hourglass-shaped deck and featuring helical ramps and curved connector spans at each end — a bridge with no straight lines.
