Why was the old Sixth Street Bridge demolished?

Last updated October 24, 2021 by ZagBot Comment

The Sixth Street Viaduct bridge between the Boyle Heights neighborhood and the Arts District in downtown Los Angeles, California, was demolished in 2016 because of concern about its ability to withstand a major earthquake event.

Constructed in 1932, the condition of the iconic arched concrete bridge over the Los Angeles River was deteriorating because of an alkali-silica reaction caused by the high alkali content of the concrete. This resulted in cracking and weakening of the structure to such an extent that it could collapse in the event of an earthquake.

A new viaduct bridge is under construction and scheduled for completion in mid-2022, which features ten pairs of illuminated arches, wide sidewalks, bicycle lanes, and a new 12-acre park beneath the structure.
