Additions and Alterations (1102.2)
Highway maintenance and improvement projects vary widely in scope. It is
important that there are clear and well defined rules for which requirements
will apply to a particular type of highway improvement.
Alternate Circulation Path (1102.3)
There are times when it is not feasible to provide an alternate circulation path
during construction due to right of way restrictions, construction staging and
other reasons.
Pedestrian Access Route (1102.4)
The adjoining municipalities typically fund any sidewalk improvements that are
included on our projects. As a result, a sidewalk may not be continuous
throughout the length of a project. What bearing will these guidelines have on
determining sidewalk termini when there may be multiple agencies involved in
funding the construction? If the entire length cannot be constructed between two
defined termini, what portion should be built?
Pedestrian Crossings (1102.8)
The 2% maximum profile grade called for to achieve the 2% maximum crosswalk
slope is more restrictive than the 3% maximum grade recommended (6% allowable in
some circumstances) for intersection approaches per AASHTO. The creation of
these 2% "tabled areas" could result in a substantial project cost increase.
Vertical Access (1102.12)
Many underpasses in our area are constructed under bridges along creeks and
rivers, and are located in the floodplain. If grade and elevation requirements
cannot be met, it does not seem to be a good idea to construct an elevator in a
floodplain.
