Hoover Dam Bypass Bridge Construction Time Lapse

Required Clearances and Widths

These are some requirements I will need to incorporate into the design. The required vertical height clearance for this bridge will need to be 5.5m above all paved surfaces. The width for two directional cycle and pedestrian traffic is a minimum of 3.5m and the maximum slope for wheel chair accessibility will be 1:12.

Wheel Chair Accessibility

I would like to incorporate wheel chair accessibility into at least a portion of the bridge design. I found the "Americans  with Disabilities Act and Architectural Barriers Act Accessibility Guidelines" home page. There is some in depth rules and guidelines that seem to be in place for new construction in the United States. See the link on the right.

Thesis Questions

1) Where would be the best placement of a bridge over Summit Drive to encourage use by pedestrians, cyclists and users with mobility disabilities?

2) How can CPTED principles be incorporated into the design of the bridge and surrounding areas?

3) How can the design of the bridge and surrounding areas incorporate community priorities such the "Tournament Capital City" initiative?

Locations for Bridge Proposed by City

Redefining Research Project

I have decided to try to focus my research project a little bit.
I plan on just using the site at Thompson Rivers University for my bridge design. Im apparently not the first person to consider this as a great location for a pedestrian bridge. It turns out that the City of Kamloops has already initiated a process that will look at a bridge in this location. I plan to use some of the criterea listed by the city as part of the design process, but as a student, I obviously will not have the resources to create a complete proposal.The following is a portion of the RFP from the City of Kamloops:

Summit Drive
The 2010 Bicycle Master Plan also identified a grade separated multi-use pathway connection across Summit Drive north of McGill Road. The City requires the predesign of this connection in order to properly budget for the project as well as apply for funding from more senior levels of government.
Substantial volumes of vehicle and pedestrian traffic at the intersection of Summit Drive and McGill Road have increased delays at the intersection. Concerns for the safety of pedestrians have been brought forward to the City and Council with regard to the volume of jaywalking that occurs on Summit Drive north of McGill Road. The overpass must serve pedestrian and bicycle demand from Dalgleish Drive as well as pedestrian demand from the sidewalk along McGill Road. There are potential property and right-of-way limitations that need to be addressed. The project may require options, depending upon the City's ability to acquire right-of-way. Further details on the Summit Drive overpass can be found in Appendix "C" of the City's Bicycle Master Plan.
As with the Peterson Creek Multi-Use path, there are many potential alignments for
this connection. Again, the City requires at least three alignments to be identified.
For each alignment, the successful proponent will prepare a summary of high-level
issues and order-of-magnitude costs. Suggested alignments are shown in Appendix
"C". Each option shall identify the proportion of use for bicycle and pedestrian traffic
as well as typical daily volume when Thompson Rivers University is in session. It is
expected that the proponent's submission will include a detailed methodology to
determine these volumes; mode share will influence the design and location of the
overpass. Using this information, a preferred option will be recommended. Then,
after approval from the City, the successful proponent will undertake the predesign
of the preferred option. A recommendation on treatment of pedestrians at the
intersection of McGill Road and Summit Drive is also required (i.e. impacts of closing
the north crosswalk at this intersection).

The predesign shall:
• Provide a Class C estimate;
• Include plan and profile, cross-section, and structural drawings (prepared by
a qualified structural engineer) to properly develop the Class C cost estimate;
• Identify phasing options to provide flexibility in the funding and construction
of the project (cost estimates required for each phase);
• Address geotechnical conditions;
• Include the design of all required pathway connections to the proposed
structure;
• Identify all necessary environmental permits and propose solutions to any
foreseen issues;
• Address lighting and power source requirements;
• Identify utility conflicts and propose solutions; and
• Address existing drainage issues directly related to the overpass project (a
complete drainage analysis is not required).
