This is the Transportation Planning Board's documentation of the Financially Constrained Long-Range Transportation Plan (CLRP) for the National Capital Region approved by the Board on October 15, 2014.

The CLRP identifies all of the regionally significant capital improvements to the region’s highway and transit systems that area transportation agencies expect to make and to be able to afford over the next 20 plus years. It also outlines all anticipated spending on operations and maintenance of the current and future transportation system over the same timeframe.

The TPB amends the CLRP each year to include new projects and programs and to make changes to projects already in the plan. Visit the CLRP Amendment page to learn more.

The investments in the CLRP aim to meet the
mobility and accessibility needs of the region now
and into the future.

  • There are more than 500 regionally significant
    capital improvements adding or removing highway
    or transit capacity and therefore might affect future
    air quality. In all, the plan includes nearly 1,200
    new lane-miles of roadway and 44 new miles of
    rail transit.
  • The financial plan identifies a total of $244 billion
    in available revenue to build, operate, and maintain
    the transportation system spelled out in the CLRP.
  • Emissions of four key pollutants regulated by
    EPA are expected to remain below approved
    regional limits.
