    Default Maryland SHA bike design guidelines

    MD -- SHA Bicycle Design Guidelines 2012.pdf

    This may be of interest only to infrastructure geeks, but SHA has a new comprehensive report on designs for bike infrastructure on or alongside state roads. It's a pretty big PDF, with a lot of design graphics.

    Here are some of the intro clips:

    Policy:
    It is SHA’s goal to provide these
    accommodations as part of all roadway projects where it is appropriate and feasible to do so.
    Creating a regional bicycle network that connects both on-road and off-road facilities to transit
    stops, key community destinations, and other bicycle traffic generators and destinations is critical
    to moving Maryland towards a complete multi-modal transportation system. As SHA develops this
    system, it is imperative that we make our facilities as safe and efficient as possible for all roadway
    users. To this end, recognizing the potential safety concerns of mixing bicycles with motor vehicle
    traffic, SHA endorses the creation of a statewide bikeway network to increase motorist awareness
    and acceptance of bicyclists as legitimate roadway users and to actively promote safe bicycling
    along our highways.

    Compliance:
    1.3 ComplianceCertification
    All proposed activities which disturb the paved roadway area, disturb the adjacent curbline, or
    adjust the line striping shall be reviewed for bicycle accommodations. These proposed activities
    include, but are not limited to, replacing and/or modifying lane widths or shoulder widths. Every
    effort shall be made to narrow the travel lanes in order to widen the shoulder to improve bicycle
    compatibility. Prior to construction, the Assistant District Engineer (ADE) for Traffic will approve
    the activities and verify that bicycle accommodations have been met as outlined in this policy.

    Waivers:
    It is SHA’s intent to provide bicycle accommodations on all roadways under its jurisdiction where
    bicycles are allowed. However, if it is determined that full bicycle accommodations cannot be
    provided, a design waiver shall be requested. A project can only proceed to advertisement or
    construction (construction includes maintenance activities), if the project provides either full
    bicycle accommodations or has been granted a design waiver. Noblanketdesignwaiverswillbe
    granted on a projectwide or programwide basis. To avoid schedule disruptions late in a
    project’s development, waivers should be submitted along with the conceptual scope approval
    (Design Approval Memorandum or equivalent process). If during construction, it is found that a
    project element cannot be constructed to meet full bicycle accommodations, a design waiver shall
    be obtained prior to commencing work.
    A design waiver may be considered for such things as impacts to right of way, utilities, structures
    (such as bridges and drainage structures), environmentally or historically sensitive areas, or due to
    excessive cost. Cost shall not be the sole consideration unless the inclusion of bicycle
    accommodations increases the project budget (ROW, utilities, and construction) and cause adverse
    impacts to the overall project funding. A waiver shall not be requested until all reasonable
    alternatives to providing full bicycle accommodations have been exhausted and documented. The
    significance of additional impact created by these alternatives over and above the basic project will
    be considered in the waiver decision. The documentation of these alternatives will be required to
    support the design waiver request.
    Design waivers are not intended to exclude the implementation of bicycle facilities as part of a
    project. Even with the design waiver, a project shall still be designed as close as practical to provide
    full bicycle accommodations.

    This is the type of provision that made Florida's similar guidelines almost useless. On every project bicycle facilities would be deemed infeasible. It's all in the application though.

    Thanks for the link, it'll be interesting reading.
