From conversations with insiders, I have learned that these bollards are being installed without consensus among staff and against the recommendations of some staff with cycling expertise. In any case, they are being installed without community input and without any input from the Arlington Bicycle Advisory Committee, of which I am a member. I have previously posted about how bollards are mostly unnecessary and often create more problems than they solve.
(UPDATE: I made comments to the Arlington County Board on May 19. Text of my remarks is here.)
The new East Falls Church bridge went into service last month, and about a week later four bollards were installed: three at one end and one at the other. These three went in first:
Then the other one was installed on the other end:
These bollards are senseless. The intent of bollards is to prevent unauthorized encroachment of motor vehicles on trails. Since these bollards are not at the intersection of a street and a trail, they do not serve their intended purpose. It's not clear what the purpose is, other than to create an impediment and hazard to trail users.
I observed a mother with two young children attempt to navigate the turn off the W&OD onto this bridge the other day. The young, inexperienced cyclists did not strike the bollards, but I could see they made them nervous. Watching that, it is an absolute certainty that less experienced riders are going to strike these bollards and fall down at some point in the future.
It appears that the bollards on the east end of the bridge are actually out of compliance with ADA (Americans with Disabilities Act), due to the spacing between them.
The Federal Highway Administration has guidance on its website regarding bollards. These bollards violate almost everything in that guidance, particularly the first bullet:
Even "properly" installed bollards constitute a serious and potentially fatal safety hazard to unwary trail users. In addition, no bollard layout that admits bicycles, tricycles, and bicycle trailers can exclude single-track motor vehicles such as motorcycles and mopeds. For these reasons, bollards should never be a default treatment, and should not be used unless there is a documented history of intrusion by unauthorized cars, trucks, or other unauthorized vehicles. (emphasis added)I am unaware of any "documented history of intrusion" at any of these locations. No bollards should be placed anywhere until it is determined that the risks of injury posed by them is outweighed by the benefits of deterring encroachment.
Another bullet reads:
Unjustified bollards can create liability exposure. Trail managers should consider whether or not they increase their liability if they install bollards, gates, fences, or other barriers.Since these bollards are all unjustified, the County is putting itself at risk by installing them.
For these and other reasons, the W&OD trail removed all its bollards more than 15 years ago. They do occasionally experience encroachments, but have determined that the hazard risk imposed by the bollards is too great to justify their presence. I hope that Arlington will also adopt a similarly enlightened attitude.
