Work on 13R-31L started in 1962 with the demolition of the structures that occupied the runway site. A number of former WWII army barracks (DAL
was used as a military field during the war) were located on the southern half of the new runway site, along with some homes. A few hangars and warehouses occupied the northern portion, closer to Bachman Lake.
Lead-in lights were installed on the 31L end, literally snaking between the warehouses beyond Mockingbird Lane (those lights are still there today.) Sequenced flashers were also placed on the 13R approach, although the system was not as elaborate as the one installed on 13L.
The runway opened in April of 1965. It had been on the drawing boards since the late 1940s, and was finally constructed in large part to compete with Fort Worth's Greater Southwest International Airport. By doubling Love Field's airside capacity, Dallas essentially put the final nail in GSW's coffin - although GSW extended its main runway across Highway 183 in 1964 in an attempt to attract more jet traffic.
Within weeks of the runway's opening residents at the north and south end of the strip had filed lawsuits against the city of Dallas. The situation was especially bad at the northern end, where effluent from jet engines killed the trees in peoples' yards and interfered with television reception. A few people reported that the shingles had been shaken off their roofs.
Ironically enough, the new runway was supposed to REDUCE the noise over homes near the airport by routing aircraft away from the neighborhoods east of Love Field. Instead, the western neighborhoods now got an equal amount of noise.
Today, of course, the situation isn't as bad. Some of the homes immediately north of the runway (along Northwest Highway) were demolished to create a clear zone, and Southwest's 737s are much quieter than Braniff and American's 707s ever were.
I wish I could have seen those days...
