Another bridge railing

I was riding my bike over the Longfellow bridge and thinking about the Western Ave & River St bridges and alternate designs for the sidewalk and railings.

Longfellow, which is beautiful bridge, uses the configuration shown below that could also be used on the re-built Western and River St bridges - a strong barrier between the road and sidewalk with an artistic railing on the other side of the sidewalk.

As part of the Longfellow reconstruction that will start next year and is a "signature component" of the same Accelerated Bridge Program that will rebuild the Western & River St bridges, "the bridge's ornate pedestrian railings will be restored or replicated". Western & River have solid concrete walls instead of ornate pedestrian railings, and their reconstruction is the perfect opportunity to replace them with something more beautiful.
