With the right-of-way and funding secured, work on the trail began in the early 1990s with four separate sections. Before any of the formal work began, volunteers built a wooden deck over the Arizona Avenue Railroad Bridge in 1990. The groundbreaking for the trail was held on September 30, 1992, when Montgomery County leaders symbolically pried loose one of the railroad ties. Work then began on the first section between Bethesda Avenue and Little Falls Parkway. That section, paid for by Montgomery County departments of transportation and parks, and businessmen John Ourisman and Tom Miller, was cleared by PEPCO in exchange for easement considerations elsewhere and to reimburse the community after residents complained about power-line work on nearby Arlington Road. It was the first section to open when the ribbon was cut on March 30, 1994. Work on the portion in the District, from Dalecarlia Reservoir to Georgetown, except for the Arizona Avenue Trestle, started in 1993, finished in late 1994 and was performed by the National Park Service. That same year, Montgomery County, with financial assistance from Maryland and the federal government and planning from the Maryland-National Capital Park and Planning Commission, built the section from Little Falls Parkway to MacArthur Boulevard. Removal of the tracks was done in the spring, paving in the summer and the section was completed by the end of the year. In late 1994/early 1995, Arlington County built the section of the trail near Dalecarlia Reservoir from MacArthur to the District line, because they were doing unrelated work on pipelines in the area. In late 1995, the concrete deck of the Arizona Avenue trestle was poured, replacing the wooden deck built 5 years earlier. In June 1996 the Arizona Avenue Trestle was opened and in November the trail bridge over River Road followed. The last piece of the trail to be completed, the Dalecarlia Bridge includes a component of a bridge which formerly took the Georgetown Branch over the Washington and Great Falls Electric Railway and it was designed to go over a road connecting two parts of the Washington Aqueduct reservation. Although most track removal was completed a few years earlier, the first three miles of the line from Silver Spring to Bethesda remained tracked until 1996, the rails not being removed until the summer of that year and in December of that year, dedication ceremonies formally opened the River Road Bridge, the Dalecarlia Bridge and the full Capital Crescent trail.
