A major milestone has taken place in the Michael Maltzan Architecture-led effort to replace Los Angeles’ iconic 6th Street Viaduct. 

Construction Drive is reporting that the falsework has been removed and the first of ten spans successfully installed on the $588 million project that will eventually connect Boyle Heights to the Downtown Arts District. The installation paves the way for the disruptive six-year-long build’s much-anticipated completion, which is still on track for the end of the summer. 

The bridge is one of the largest such construction projects to ever take place in the city and is seen as an important step in the connectivity improvements of the Boyle Heights community. Engineers will now begin work closing the superstructure before they can start on the installation of hangers for the next span, according to a press release from the international engineering concern COWI, that is leading the process.

“If you consider each arch span as an individual bridge, then this essentially marks the completion of the first of ten bridges — making this such an exciting milestone for the project,” project manager Tobias Petschke said in a statement. “This is a really exciting time to be an engineer. Having the opportunity to apply our expertise to projects of this kind reminds you just how important our work is.”
