Additional improvements to the street were made throughout the 19th century: The avenue was macadamized in 1832 (and the poplars removed), repaved with round stones in 1852, and repaved with wooden blocks from 1st to 15th Streets in 1870. The wooden blocks required such extensive repair, however, that between 1876 and 1877 they were replaced with rock from 1st to 6th Streets NW, and with grahamite asphalt from 6th to 15th Streets NW. The avenue was repaved in 1890 and again in 1907.
