[edit] Stages of construction
It would be interesting to supply dates for when the road was improved. It was widened to 4 lanes in stages (dates approximate - need source):
- initially a few miles from both ends in early 1960s (before 1964). On the south end, only to the town limits of Indian Head. On the north, as part of the construction of the Capitol Beltway (probably 1962 or 1963).
- extended on both ends during the late 1960s (to the Charles County line on the south, and to Old Fort Road on the north).
- sometime after the late 1970s, it was widened the remaining 10-15 miles.
