A 1948 city map shows South Main Ave. dead-ending on the north edge of the old U. S. Arsenal property at current day Cesar Chavez Blvd. On the south side of the Arsenal, the street, which eventually became the southern extension of South Main was named Bois d’arc. Bois d’arc ran just two blocks from Arsenal Street to Johnson Street then it became Frasch Street until it dead-ended on South Alamo.

A February 20, 1949 article in the San Antonio Light announced the opening of the Main Street extension through the Arsenal property. “This will be the first section to be completed of the proposed Main Ave. extension which eventually will be projected to South Alamo St.,” said James W. Knight, city street commissioner. The new section that cut through the Arsenal is 30 feet wide and 953 feet long.

Only 8 of 52 pieces of property remain to be purchased for the right-of-way to complete South Main from Arsenal St. to South Alamo, Knight added.
