from north of Baltimore to south of DC, in the middle of the night, so traffic's not a factor.
A) 95 south......895 south.....295 south (Baltimore-Wash parkway)... back on 95 south
B) 95 south straight through
option A seems more direct but speed limits could be a factor
a slight change of option A could be 95 south to where it meets 295 (instead of using 895)
