***UPDATE***
Alert cyclist Brent noted that the bicycle ramps have had a entry ramp added – see picture: 
Back-story – The revitalization of the Corning Riverfront Park proceeds apace. The “finishing touches” are nearing completion. The new “green path” is open or will be soon so that people on bicycles can ride from the Slater to the Barge/DGS building without having to navigate amongst the walkers, joggers, and strollers. At Colonie/Water Sts., a second segment helps riders get clear of the Corning Riverfront Park and across the I-787 exit ramp. [Ed: Be careful here!]
Alert cyclist Brent reported that bicycle ramps are installed on the stairs leading to and from the Corning Riverfront Park over the bridge that crosses I-787 at Pine St. on Broadway. Now, instead of carrying one’s bicycle up or down the stairs, one can walk it up or down the ramp. As a cautionary note, lean your bicycle away from the hand railing to prevent interference with the pedals.

The ramps help those whose bicycle weight or degree of fitness makes climbing/descending the stairs a chore. In addition, those who want to enter the Corning Riverfront Park WITHOUT risking the Jose Perez Memorial Plaza (at the Slater entrance) or the I-787 off ramp (at Colonie St.) or who are in midtown, can now use the pedestrian bridge (with ramps) as a good alternative. Notabley, people on bicycles can access the Corning Riverfront Park from either end by using the BikeAlbanyMap. 
The ramps are a good idea. Nevertheless, check the motorized “bicycle lift” in Trondheim – a good idea for the State or Morton St. hills?
