Traction Power Substation Installation Scheduled for 2nd/H Streets NE

Two-Block Section of 2nd Street NE Closed to Traffic on September 28, 2013

The DC Streetcar construction team plans to install a traction power substation (TPSS) inside the enclosure under the Hopscotch Bridge at 2nd Street NE on Saturday, September 28th.
The TPSS installation represents noteworthy progress toward completing the H Street/Benning Road segments of the DC Streetcar system. The 2nd Street TPSS is the first of three substations to be installed; the others are at sites on the southwest corner of 12th and H Streets, and at the Car Barn Training Center along Benning Road NE north of 24th Street. The substations provide electrical power to the streetcars through the Overhead Catenary System (OCS).

The 2nd Street installation requires closing a two-block section of 2nd Street – between G Street and I Street – to vehicular traffic on Saturday, September 28th from 7:00 am to 7:00 pm. Local traffic will be permitted and access to the Kaiser Permanente Capitol Hill Medical Center and to the parking garages under the Hopscotch Bridge will be maintained. Pedestrian access along 2nd Street will be maintained; however, there will be two 15-minute periods of interrupted foot and vehicular traffic as the TPSS is unloaded and positioned inside the enclosure.

The substation is a prefabricated structure measuring 36 feet long and 20 feet wide. It will be delivered in two sections on flatbed trailers and unloaded by a large crane.

During the street closure, southbound 2nd Street traffic at I Street will be diverted east on I Street, then south on 4th Street, then west on G Street to return to 2nd Street. South of the work zone, northbound 2nd Street traffic will be diverted east on F Street, then north on 5th Street, then west on K Street to return to 2nd Street.
