Purple Line construction crews lower arches onto bridge span in Chevy Chase

Construction crews lowered parts of a bridge into place overnight along a span of the Purple Line light rail project in the suburbs of the nation's capital.

A video posted online shows metal arches dropped into place on the bridge over Connecticut Avenue in Chevy Chase.

The Purple Line is a 16-mile light-rail line with 21 stations that will extend from Bethesda in Montgomery County to New Carrollton in Prince George's County.

Officials expect the multi-billion dollar project to begin carrying passengers in fall 2026, which would put it more than four years behind schedule.
