The District Transportation Access Portal (DTAP) provides a wealth of performance data and project information about District Department of Transportation (DDOT) projects in an easy-to-use dashboard format. DTAP’s interactive mapping tools help identify roadway and infrastructure conflicts between DDOT and other public space users. Although this website provides a forecast of DDOT's upcoming construction projects, the official solicitations are posted on the Office of Contracting and Procurement's (OCP) Solicitation Listings webpage. The Government of the District of Columbia requires potential contractors to submit specific documents and certifications prior to the awarding of a contract. These required documents can be downloaded from the Solicitation Document list.
