McMillan Construction Brings Traffic Impacts to First Street

January 16, 2014

(Washington, DC) – DC Water is performing construction activities on First Street, NW as part of the McMillan Stormwater Storage Project.

From Monday, January 20 through the week of Monday, February 3, First Street between Channing Street NW and Michigan Avenue NW will remain closed to both northbound/southbound traffic. It is advised that North Capitol Street be used as an alternative route for travel on First Street.

Important Information:
* During the First Street closure, dump trucks leaving the work site will need to follow a modified hauling route to include travel southbound on First Street, turning eastbound on Bryant Street and proceeding southbound on North Capitol Street.
* As drilling operations continue, additional equipment will need to be brought on site. Delivery of the equipment will be handled using several flat bed trucks. The scheduled date for delivery will be Friday, January 17 between 9:30a.m. and 3:30p.m. The delivery trucks will travel northbound on North Capitol Street, westbound on Michigan Avenue and southbound on First Street.
* Construction operations for all partial road closures will be from 7:00am to 7:00pm, Monday through Friday; construction operations for all full road closures will be 24 hours, Monday through Saturday.
* Temporary traffic signs will be set up throughout the area to alert motorists to the upcoming traffic changes.
* Some traffic delays within the vicinity of the work zones are anticipated.
* Sidewalk detours will also be implemented.
* There will be an increase in truck traffic.
* Noise levels will be closely monitored during construction.

Project Details
DC Water will construct two underground structures to divert stormwater into a temporary holding tank within the McMillan Sand Filtration Plant and existing trunk sewer. The two diversion structures at North Capitol Street and First Street will work together with the retention basins along Irving Street to delay approximately 4.5 million gallons of stormwater from reaching the Bloomingdale and LeDroit Park neighborhoods during heavy rainfall events.

This is a two-phase project. The first phase, completed in 2013, included removal of sand from two tanks. The second phase of the project is currently underway, and includes work on North Capitol Street, First Street and Irving Street.

DC Water will be doing construction as part of a sanitary sewer rehabilitation project on Clara Barton Parkway in Maryland from Sept 8 - Oct 10, 2025, which may cause delays inbound near the I-495 Beltway interchange. One lane will be closed in the work zone to reline an 800-foot section of the sewer line, known as the Potomac Inteceptor. Access to the inner and outer loops of the Beltway will remain available. Additional lane closure may be necessary intermittently through Oct 31, 2025.
