It's a leftover from a different design for the roads there.

When it was originally built, that lane didn't exist on Bow Trail west of 14th Street and it was the on-ramp for vehicles entering Bow Trail from southbound 14th. Over the years, the interchange has undergone changes and the current 14th St on-ramp was built in the early 90s and the second bridge just became the third lane on Bow Trail.

The separate bridges over 14th St have been there for over 50 years, since Bow Trail was first built.

The city's historical aerial photos are always a nice resource to use when trying to figure out why things were built the way they were: https://maps.calgary.ca/CalgaryImagery/
