RE: Route 100 Plan Comments
- In general, we are favorably impressed with the attention to bicycle and pedestrian accommodation proposed for this corridor at this point in the process. We like 11 foot travel lanes with 5 foot shoulders; FHWA notes that speed reductions often follow lane width reductions.
- We have some concerns about the preliminary drawings that show “bike lanes” painted to the right of travel lanes where right turns are permitted. Such a placement puts through-riding bicyclists at greater risk for right hook crashes. At a minimum, we would suggest the inclusion of “Turning Vehicles Yield to Bicycles” signage at such locations.
- We also have concerns about how the preliminary images show “bike lanes” painted as if they were shoulders (i.e. with wrap around lines at intersections, rather than with open ends to indicate that these are bike facilities with entrances and exits). These drawings suggest that the “bike lanes” are actually shoulders. Are bike lane stencils planned for these 5 ft lanes?
- We endorse any traffic calming measures that can be safely engineered into the designs, especially at intersections and trail crossings, including Rapid Flashing Rectangular Beacons, traffic islands, and robust paint markings. FHWA notes that speed reductions often follow lane width reductions, and MaineDOT has endorsed 10’6” travel lanes in some situations.
- While we applaud the inclusion of more sidewalks in the project area, we have concerns over (if we understand the plan correctly) the need to cross Rt. 100 at Leighton Road to maintain access to sidewalks northbound. We recommend robust crossing infrastructure, including a dedicated pedestrian signal.
- We have concerns over the roadway width passing over the Libby Bridge. It is not clear to us what the cross section width of the Libby Bridge is, and whether it would require the shoulder/bike lanes to be dropped in order to pass over the bridge. A sudden drop of space on the road’s edge might require bicyclists to merge into the travel lane to cross the bridge, resulting in unexpected movements that might impact safety.
Thanks for the opportunity to provide comments. Regards,
