One of the first Measure DD projects, completed in 2007, was the renovation and rededication of the 1913 pergola at the north end of the lake. Several sections of Measure DD work were completed in 2008. The renovation of the 1909 Municipal Boat House into Lake Chalet restaurant was completed. Reconstruction of El Embarcadero between Grand Avenue and Lakeshore Avenue was completed. Lakeside Drive from just north of East 14th Street to 19th Street was narrowed from four lanes to two, and a bicycle lane added. Finally, new landscaping along the west side of the lake from 14th to 19th street and the east side from East 18th Street to El Embarcadero were completed. The largest part of the Measure DD work was the 12th Street Reconstruction Project on the south side of the lake. Replacement of the Frickstad Viaduct, or "12th Street Dam" (built 1950), and renovation of the roadways and tunnels between the Kaiser Convention Center and the southern end of Lake Merritt began in May 2010 was completed in June 2013. The groundbreaking ceremony for the 12th Street Project took place on May 6, 2010 near the Frickstad Viaduct.
