I am going to assume Judy's car was in tact when she entered the water.
I see no realistic points entry into the Concord River from the west side of the Concord river between Wilson Street and JC's house.
Bruce Stebbins and Hans Hug's sonar search area was between the Lawrence Bridge in Lowell & the dam in North Billerica.
There's the possibility she could have entered the river between the dam in North Billerica and where her car & remains were found in Lowell, from south of the railroad bridge.
With rising levels, rushing water flows, freezing & thawing, her car could have been moved over the 40 years down river (heading North) and broke up when going under the railroad bridge.
If she went off at the Faulkner dam bridge on Faulkner Street in North Billerica, her car and her body would have to travel over 3 miles around bends & under the I-495 Bridge and the railroad bridge to where the car/her remains were found.
She could have somehow gotten on I-495 from either west or east and went off the interstate Bridge in Lowell. This bridge is just south of the railroad bridge. Her car could have broken apart if it went off here and flowed possibly in parts the short distance under the railroad bridge to it's most current resting place.
Providing her car did not break up from going under the railroad bridge and assuming time and elements are what broke the vehicle in to parts, I see no points of entry north of the railroad bridge other than:
1) The corner of Denton & Billerica Streets and
2) The town owned lot located at 135 Billerica Street in Lowell, the area where her remains were found.
Imo, looking south at the railroad bridge from the corner of Denton & Billerica (street view), it just doesn't seem possible, to me, that a car could fit (in tact) through the pilings supporting the bridge.
I could be totally wrong and way off but I'm assuming her vehicle went into the river north of the railroad bridge solely because her remains were located not far from her vehicle.
Thoughts, opinions & alternative scenarios are welcome.
