Our relatively upscale residential neighborhood was cut off from another part of the city when a limited access road was put in 15 years ago. We've been discussing the possibility of re-connecting via a tunnel of some sort, in that it's really not feasible to bridge over. However, the only way people would support this is if the tunnel is sort of low capacity and low speed, safe and bike/pedestrian friendly. We don't want it to become some roaring thoroughfare into the neighborhood, or to become a place where criminals hang out.
Does anyone know of any examples of a good looking tunnel that goes into a residential area? Or of a website where we might find some ideas?
Thanks much, and I Hope my question isn't too vague.
