Bicycle 'fly-over' Ramps

Two final options involve bicycle flyover ramps from the north side bikeway to the North Street Annex or to Gottingen Street.

Retaining the bikeway on the north side of the bridge results in the inconvenience of a circuitous route to North Street westbound and Brunswick Street, in addition to the potential for collision with the barrier fence on the circumference of the loop ramp leading to Barrington Street.A flyover ramp from the north side bikeway leading to an area between the southeast corner of Gottingen Street and Brunswick Street would provide another solution to these problems. In addition to direct connections to North and Gottingen Streets, it avoids the steeper grade of the ramp loop. It is however less convenient for cyclists wishing to use Brunswick Street. . In order to provide a convenient slope for cyclists, grade separation from the bridge deck would likely have to start fairly close to the high point of the bridge span. The flyover ramp would have to clear signage suspended sixteen feet over the bridge approach. While there is the design possibility of an architectural centerpiece at the bridgehead, the potential as a visual intrusion is high and the cost would be great.

Two ramp options are shown. The black line indicates a flyover ramp to the area near North and Gottingen. The Magenta indicates a ramp to the North Street Annex

Another ramp option is possible from the north side bikeway to the North Street Annex slip road. The natural grade favors this ramp by reducing the required length and gradient. It maintains direct access to westbound North Street, crosswalk access to Brunswick Street and destinations off Barrington Street. However, cyclists entering the bridge from North Street may be tempted to ride on the sidewalk to access the ramp. Again, the costs involved would be high.
