The District of Columbia has 265 bridge structures; 226 of the bridges are owned by the D.C. Department of Transportation (DDOT) and the remaining 39 are owned by the National Park Service (NPS). The average age of a bridge in D.C. is 58 years, and 80% of the bridges will need to be replaced or rehabilitated in the next 10 years. However, the District made significant strides to reduce the number of structurally deficient bridges from 8% to 3% in just three years. Despite this progress, more than 220,000 trips are taken over a structurally deficient bridge every day and a quarter of bridges have at least one major component in fair condition.
DISTRICT DEPARTMENT OF TRANSPORTATION
The goal of Vision Zero is straight-forward: zero fatalities and serious injuries in our transportation system, because no loss of life is acceptable. Vision Zero was first adopted in Sweden in 1997. Since then, fatal and serious injuries in Sweden have consistently declined, despite a regular increase in people driving, walking, biking, and using transit.
Earlier this year, 1st Street in Washington D.C. was transformed into a protected bike lane with a myriad of separation techniques that all seem to work very well and feel incredibly safe. About half the lane is done with concrete median prortection while other sections are done with green paint, plastic bollards and armadillos which seem to prevent traffic from encroaching on the lane. What is truly impressive is the now much more the narrow streets deliberatly funnel traffic more slowly and lead to a street that feels welcome in a Vision Zero world.

RESOURCES FOR THE FUTURE
A new mechanism to reduce urban traffic congestion that is currently gaining traction for its purported cost-effectiveness, environmental-friendliness, and positive health impacts is the adoption of citywide bicycle-sharing systems. This infrastructure provides an alternative to driving for short trips and extends the existing network of public transit within a metropolitan area. Further, bicycling infrastructure augments the environmental bona fides of densely populated urban areas (Kahn, 2010). If bikeshares reduce traffic congestion, they may provide a low-cost policy lever to reduce automobile externalities in urban areas.
METROPOLITAN WASHINGTON COUNCIL OF GOVERNMENTS
The metropolitan Washington region’s leaders have recognized the fundamental role infrastructure plays in the ability to maintain and improve the region. However, despite regional recognition of the importance of maintaining our infrastructure, infrastructure investment is often a challenge for many organizations. Officials at the federal, state, and local level must balance an enormous number of funding needs, and sufficient funds often are not available for infrastructure needs.
