1. How much would it cost to build a bicycle and pedestrian bridge alongside the existing bridge? This should be very inexpensive compared to elevating and elongating the car bridge, as the load capacity requirements are much less; and this would alleviate one of City Council’s primary concerns.
2. All the bridge designs under consideration will require elevated approaches to facilitate the raised bridge structures. How far on either side of any of the newly designed bridges would the elevations begin? It’s obvious that if the bridge is to be elevated, the ramps on either side will need to be built up.
3. What impacts will these elevation ramps have? If the elevations ARE fairly steep, the speed limit will need to be 20 mph or so, as are many of the other bridges on Marco, to ensure safety of the intersecting streets in proximity of the bridge. This is necessary so that traffic going over the bridges can see auto, bike and pedestrian traffic entering or crossing the street in sufficient time to stop. If the speed limit is going to drop to 25 or 20 mph, that will impede traffic flow on Collier, especially during ‘Sseason’, and in light of the planned expansions on ‘Hotel Row’ further South.
It seems likely that this will cause traffic tie-up’s; and that could be very detrimental if the island were evacuated due to hurricanes, etc. If the elevations are not steep, but built up gradually, it seems very likely that the bridge approaches will have an impact on the intersections of Collier and Elkcam, the entrance to the Esplanade, the entrance to the Church, the intersection with Tigertail, Winn Dixie, Veteran’s Park, etc.
