RiverWalk is beautiful. Planning is happening to continue it under the Tappan Zee Bridge. Edge-on-Hudson will fill in another lovely segment, bringing it to the southern half of Kingsland Point Park. But in the northern half of Kingsland and up to Rockwood Hall, people need to walk and bike on streets, most of which don't even have sidewalks.
There are simple, low cost solutions for completing RiverWalk in Sleepy Hollow so everyone can enjoy it, kids and adults alike. As a bonus, these steps will make it safe and enjoyable to walk and bike to the Philipse Manor train station as well as to work at Kendal-on-Hudson, Phelps Hospital and Regeneron.
"Advisory shoulders" (photo right) is a possible way to improve walking and cycling access on various Sleepy Hollow Manor streets.
The most effective way to complete the trail between the Manors is making Riverside Dr usable only by people walking and cycling. This will make Sleepy Hollow Manor and Philipse Manor more pleasant and safer by reducing the real and present danger, noise, and pollution from cars. People who insist on driving through the neighborhoods can do so via Broadway.
Getting in and out of Kingsland Point Park from the north involves passing over three bridges, just one of which has a (narrow) sidwalk. So right now, people walking have to do so on the road. Folks with little kids need to watch them like a hawk.
There are two options for making it safe for people to walk and bike through here. One involves lots of expensive construction. The other involves moving the access point to the middle of the park, via Edge-on-Hudson, and then using the old roadway as the RiverWalk.
