Currently the A16 runs from junction number 8 to junction number 65. This leads to speculation that the southern end of the motorway is intended to be extended either directly south by upgrading the RD301/RN1 to meet the A1 at
Saint-Denis, Seine-Saint-Denis, or to the east by upgrading the RN104 to meet the A1 at
Paris-Charles De Gaulle, thus completing the missing junction numbers. ==References==
