Fish Hatchery Road - temporary concrete barrier and bicyclist protection

State WI
Description Text

The message below is from one of our project teams.  We would appreciate your feedback.


We are looking to modify the standard temporary precast concrete barrier to provide protection to bicyclists during reconstruction of the Fish Hatchery Rd bridge over the beltline.  As seen in the attached plan sheets, we have a 4' wide bike lane next to temporary precast concrete barrier during Stage 2 and 4 of construction.  We propose modifying the barrier by adding chain link fence to the outside face of barrier to provide a minimum 42" high combination barrier / fencing.  Given the 30 mph speed limit, need to protect bicyclists from falling onto the beltline, and temporary nature of this condition, we believe this to be a reasonable solution.  Please let us know if you concur.

We have found some a reference involving the chain link fence on concrete barrier:

Some other pedestrian rail reference suggestions include:

Washington State has a list of approved pedestrian rails, and I'm not sure some of these have been crash tested. Maybe so, but they don't give federal approval letter notice or reference to a crash test.



TXDOT has their own pedestrian rail, but once again no crash testing
