Pont d'Alma tunnel
 

What bus route # in Paris would take one through the Pont d'Alma tunnel in the direction she was headed during her fatal accident?

What a gruesome interest!

No bus goes through that tunnel. they stay up on the surface where the bus stops are.

You should also know that big fences were built to prevent pedestrians from creeping down to the tunnel.

And don't try following the route in a white Uno...

And make sure your driver isn't drunk and that your seat belt is done up.
