Washington Metrorail platforms to get $400m makeover

Washington metropolitan area transit authority Metro has announced a multi-year project to reconstruct outdoor platforms at 20 Metrorail stations using shutdowns instead of prolonged single-track operation.

The three-year capital project will address structural deficiencies after decades of exposure to the elements. At many of the stations, temporary measures have been installed to stabilize the platforms to ensure passenger safety until reconstruction can take place.

The project is estimated to cost between US$300m and US$400m and will be the first major construction project to benefit from dedicated capital funding recently approved by the legislatures in Virginia, Maryland and the District of Columbia.

Rebuilding the platforms will require tracks be taken out of service to allow for heavy construction activity, including demolishing existing structures and placing concrete.

Metro has already rebuilt platforms at 10 of the system's 45 outdoor stations; however, the process used previously resulted in years of single tracking and customer inconvenience. Rebuilding the two most recently reconstructed platforms, at Minnesota Avenue and Deanwood stations, took approximately three years.

Following extensive internal planning and consultation with construction contractors with the goal of minimizing customer impact, Metro has developed a program that advances the reconstruction of the next 20 platforms primarily using extended shutdowns during summer months - rather than single tracking - to provide contractors with 24-hour access to selected sites.

The approach is described as improving safety while significantly reducing project duration because workers do not have to repeatedly set-up and break down their equipment.
