701 Pennsylvania Avenue

Founded by Brigadier General William W. Averell, the Grahamite Asphalt Pavement Company was pivotal in pioneering the use of asphalt for road surfaces in the late 19th century. After extensive experimentation, the company successfully paved notable thoroughfares such as Fifth Avenue in New York City and Pennsylvania Avenue in Washington, D.C.

Averell's innovative approach led to the granting of multiple patents for improvements in asphaltic pavements, significantly enhancing the material's applicability for urban infrastructure. His ventures not only transformed road construction but also involved numerous legal battles to protect his inventions, culminating in a substantial monetary award in 1898.
