Public Works Administration (PWA) was immediately established to disburse the funds appropriated by the act. The District of Columbia received a $1.9 million grant for road and bridge construction, and the city said on July 8 it would use a portion of these funds to finish Constitution Avenue. Construction on the $200,000 project was scheduled to begin at the end of August 1933 and employ 150 men. Part of the PWA grant included funds for the completion of John Marshall Park, at the intersection of 4th Street NW and Pennsylvania Avenue NW. Along with construction of the park, the city finally linked the two ends of Constitution Avenue by turning the western section slightly northward, and the eastern section slightly southward. The one-block section of Pennsylvania Avenue NW between 4th and 5th Streets was renamed Constitution Avenue (leaving Pennsylvania Avenue no longer contiguous). To control these two intersections, 10 traffic signals (some of the first to be installed in downtown D.C.) were placed at these intersections. The intersection opened on August 17, 1933. The lack of uniform width along Constitution Avenue proved problematic. With little fanfare, the city began widening the entire roadway to . In September 1933, the city received the first disbursement of revenue from the federal gasoline tax. This tax was imposed in the Revenue Act of June 1932. The city used $30,494 in PWA grant money and $45,741 in federal gas tax revenue to widen Constitution Avenue to the full width between North Capitol Street and 2d Street NW. This project, which occurred in conjunction with clearance of Upper Senate Park, began in late September 1933. City officials also asked the CFA to approve widening of Constitution Avenue to the full width between Virginia Avenue NW and the Potomac River. The CFA quickly approved the project. Paving of the fully widened street began in October 1933 and continued in November. In December, the avenue neared completion with the installation of traffic lights between 6th and 15th Streets NW. Constitution Avenue terminus The western terminus of Constitution Avenue is the Theodore Roosevelt Bridge; thus, Constitution Avenue connects the city's ceremonial core with Interstate 66. The eastern terminus is at 21st Street NE, just west of Robert F. Kennedy Memorial Stadium. Through traffic is diverted via North Carolina Avenue NE and C Street NE to the Whitney Young Memorial Bridge. Route numbers Between Louisiana Avenue and Interstate 66,
