The three finalists to rebuild the Sixth Street bridge linking Boyle Heights and downtown unveiled their plans and ideas earlier this week for the $400 million project. The 80-year-old concrete and steel structure officially known as the Sixth Street Viaduct is slowing disintegrating from inside as a chemical reaction eats away at the concrete of the 3,500-foot-long span.
The Downtown News said the entry by HNTB that features 10 large arches probably has the most “wow factor” of the three but all the proposals also addressed the demands for more pedestrian and bike access as well as making use of the land below the bridges.
Two more presentations are scheduled for Monday night in downtown and Tuesday night in Boyle Heights. Click here for details.
Proposal by HNTB: “We have separated bicycle traffic from the adjacent vehicular traffic, with a dedicated zone on both sides of the bridge separated both by a barrier and in section, creating clear views for cyclists as they cross. In addition to bicycle connectivity at each of the bridge’s ends, cyclists can descend to the river at the project’s center, linking to the promenade along its western embankment. To the east, a gradual ramp link’s the new green belt of Viaduct Park to Hollenbeck Park and Boyle Heights.”
Proposal by AECOM: “In addition to the walkways at deck level, a separate pedestrian link is suspended beneath the bridge over the Los Angeles River and the railway tracks to provide a direct connection between Mesquit Street on the Arts District side with South Mission Road in the Warehouse District.”
Proposal by Parsons Brinckerhoff: The cable bridge features a main support structure that resembles a pair of wings. A pedestrian walkway would run down the middle of the bridge and a viewing area would be located under the structures.
