What does it take to create a new link within an existing community? For our Houston designers, they have been hard at work for more than the past decade in creating a city-wide green system of Bayous and pedestrian trails for environmental—as well as social—good. And now, the famed Buffalo Bayou is getting another pedestrian bridge. In addition to creating ways to mitigate the wet landscape of this urban area, the park features a series of five bridges that cross the Bayou and connect neighborhoods together. The first pedestrian bridge over Buffalo Bayou was built at the Hobby Convention Center back in 2005 as part of the Buffalo Bayou Promenade. The Rosemont Bridge was built next in 2009 and opened in 2010 to great success.
Today, we spoke with Tim Peterson, Kevin Shanley, Josh Lock, and Scott McCready as they take us behind-the-scenes of the next bridge as it goes up between the Houston Heights and Montrose neighborhoods in Houston.
What’s the name of this next bridge and where is it located?
The Jackson Hill Bridge spans Buffalo Bayou just west of Waugh Drive. Construction is slated to be finished by Fall 2013 and the bridge will be open to the public at that time.
How big is it?
345 Linear feet.
What is it made out of?
Weathering steel truss bridge with pressure treated pine deck.
What is remarkable about the construction process for this bridge?
The bridge is being delivered in six sections and will be bolted together in sections of two and lifted into place. The clear span across the bayou from column to column stretches 150’. Galvanized guardrails are being fabricated along with the galvanized column pylons which will extrude an additional 15’ above the bridge deck and will be internally illuminated. The lighting will shine through a pattern that will be cut into the steel pylon surfaces. The pattern represents the changing appearance of the moon during the lunar cycle. Phase 2 work includes reforestation tree planting that will be installed in the areas where vegetation was cleared to make room for the bridge construction.
Here, they show us how it works — just how, exactly, this new bridge comes to be in its new home:
The Jackson Hill Bridge is located at Waugh and Buffalo Bayou. Before construction started, the site was cleared to accommodate the crane and required machinery.
Fifty foot deep piers are filled with concrete and a matrix of rebar to anchor the structure. The Pedestrian Bridge was designed by SWA Group and RDP Engineers.
A grid of rebar reinforces the Pier Cap.
Concrete was poured into the pier cap. (more…)
