Mass Highway Engineering Directive E-09-005, August 21, 2009 reads
“Bicycle accommodation shall be in accordance with
Chapter 5 of the Project Development And Design Guide and the 1999 AASHTO Guide for the Development of Bicycle Facilities.” Bicycle lanes are
defined as portions of the traveled way designed for bicycle use,
designated by a 6-inch solid white line on the right edge of the motor
vehicle travel lane . The AASHTO guide defines a bicycle lane as a portion
of a roadway which has been designated by striping, signing and pavement
markings for the preferential or exclusive use of bicyclists. A bike lane
should be delineated from the motor vehicle travel lanes with a 150-mm
(6-inch) solid white line.”Download Chapter 5 of the Project Development And Design Guide. Bicycle

accommodation
Under Chapter 5 of the Project Development And Design Guide, desirable
bicycle accommodation is in general achieved with a 4’ paved shoulder
adjacent to a 12’ travel lane or with a 16’ shared lane (with approved
signage.) Minimum bicycle accommodation is achieved with a 15’ combined
travel lane and shoulder. A 5’ space is desirable between a travel lane and
an on-street parking lane. Alternatively, a separate shared-use or bicycle
path provides desirable accommodation.. Bicycle accommodation can also be
enhanced by providing smooth pavements, bicycle-safe drainage grates, proper
traffic control devices, signage and other similar features on less-traveled
roads. Pedestrian accommodation shall be in accordance with Chapter 5 of the
Guide. In general, desirable pedestrian accommodation is achieved with at
least one 5’ sidewalk, exclusive of curb. Minimum pedestrian accommodation
on a sidewalk is achieved with a 4’ width (exclusive of curb), where a 5’
passing zone is provided every 200’. A 3’ minimum path of travel must be
provided next to every fixture such as poles, signs, mailboxes, etc.
Pedestrian accommodation may also be provided in the roadway shoulder in
accordance with the Guide, or on a separate shared-use path. Accessibility
must be met in accordance with AAB/ADA policy and MassHighway standards.
Pedestrian accommodation can also be enhanced by providing buffer zones,
appropriate crossing locations, pedestrian signal phases and other similar
features.
