Typical pedestrian bridges aren't 150 feet wide, though. Nor do most have grass growing on them (at least, not intentionally). This is, in fact, a fairly unusual infrastructure project.
- ultrarunner 1y agoI'd imagine that once you're 150 ft wide the potential for several vehicles driving across or parking has to be considered.
- duskwuff 1y agoQuite possibly. Although I'm not sure that's even significant compared to the increase in weight when it rains, waterlogging the soil on the bridge.
