Project Overview and Objective
•   The Twenty Mile Creek Bridge was constructed
    crossing Regional Road 81 (King Street) in
    1940. King Street functions as a two-lane
    arterial road serving east-west traffic flows
•   In 2010, Niagara Region completed a
    Rehabilitation / Replacement Planning Report,
    which recommended full replacement of the
    Twenty Mile Creek Arch Bridge. According to
    the structural evaluation in this report, the
    existing structure is deficient in its live load
    carrying capacity
•   Niagara Region also undertook a biennial
    bridge inspection of all bridge structures under
    its jurisdiction in 2017, which identified
    deficiencies in the Twenty Mile Creek Arch
    Bridge and identified the need for replacement
•   The study area is located in the Town of
    Lincoln, approximately 550 m west of
    Nineteenth Street where Regional Road 81
    crosses Twenty Mile Creek

2
Natural Environment
Aquatic Ecosystem
• The fish community within Twenty Mile Creek is
  comprised of species that are tolerant of the creek’s
  warm water thermal regime
•   25 fish species are known to occur in Twenty Mile
    Creek. There are no aquatic Species at Risk within the
    study area. Grass Pickerel is a species of Special
    Concern found within the study area
Terrestrial Ecosystem
•   Species at Risk plants were identified within 1 square
    km encompassing the study area
•   One of these plants (Red Mulberry) is Endangered and
    one is of Special Concern (Green Dragon)
Wildlife
• Wildlife that is known to occur within areas that overlap
   the study area include 110 species of birds, 64 species
   of butterflies, 41 species of mammals, 15 species of
   amphibians and 9 species of reptiles
•   These species don’t occur within the study area but
    have been seen in the general area up to 10 km away

3
Archaeology
•   A Stage 1 Archaeological
    Assessment is complete
•   The preliminary results
    show archaeological
    potential along either
    end of the bridge
•   A Stage 2 Archaeological
    Assessment will be
    completed upon
    determination of the
    preferred design

4
Cultural Heritage
•  The Twenty Mile Creek Arch Bridge in Jordan Hollow is of Cultural Heritage Value or Interest
•  The bridge has design or physical value as an example of a Reinforced Concrete Rigid Frame Bridge style and
   construction method
• The bridge has historical value for its direct association with the work of Arthur Sedgwick (Chief Bridge Engineer for
   the Department of Highways Ontario)
• The Twenty Mile Creek Arch Bridge has contextual value for maintaining and supporting the character of an area as
   an historic transportation route (old Iroquois Trail)
• King Street/Regional Road 81 is part of the Cultural Heritage Landscape and with 20 Mile Creek helped contribute
   to the settlement of communities in the area
Recommendation:
• A Heritage Impact Assessment will be carried out to assess the impact of the preferred bridge design on the
   surrounding cultural heritage landscape. Recommended mitigative measures to conserve the heritage attributes of
   the resource/landscape will be proposed.

5
Transportation
•   Regional Road 81 (King Street) is a major east/west roadway
    extending from the Niagara Parkway in the Town of Niagara-
    on-the-Lake to the west boundary between the Region of
    Niagara and the City of Hamilton
•   The bridge is situated in the Jordan Valley area of the Town
    of Lincoln and Regional Road 81 presently functions as a
    two-lane arterial road serving east/west traffic flows with an
    average annual daily traffic of 5800.
•   The Niagara Region Transportation Master Plan sets out the
    strategic vision for transportation in the Niagara Region to
    ensure that future transportation needs for an integrated
    network of cycling and pedestrian facilities, transit, roads,
    and highways can be planned and budgeted for as the
    Region implements its future growth plan outlined in How
    We GROW. This stretch of Regional Road 81 is identified in
    the TMP as an infill link as part of the Strategic Cycling
    Network.

6
Structural Assessment
•   A Rehabilitation / Replacement Planning Report (RRPR) was prepared in June 2010 which recommended full
    bridge replacement.
•   Niagara Region completed a biennial bridge inspection in 2017, which identified various deficiencies, including:
    – Poor sidewalk conditions
    – Poor conditions on both east and west approach arches
    – Fair to poor condition for the center arch
    – Fair to poor soffit condition
    – Cracks, spalls and concrete delamination

7
Water Resources
•   The Twenty Mile Creek bridge can accommodate passage of a 50-year storm event (119 m3/s)
•   Based on preliminary results, the structure does not meet the minimum freeboard criteria for a 100-year storm
    event (186 m /s) at the upstream end of the crossing
                  3

•   There is low likelihood of overflow of water onto the bridge
•   If the bridge is replaced, the replacement bridge should be slightly larger than the existing structure in order to
    meet the freeboard criteria set by the Ministry of Transportation for a 100-year storm event

*50-year/100-year flow: Prediction of how often a storm event will happen
*Freeboard: Distance between the water level to the bridge

                                                                                   20 Mile Creek Watershed

Problem and Opportunity Statement
Problem Statement: The Twenty Mile Creek Arch Bridge, constructed in 1940, consists of a three-span reinforced
concrete arch rigid frame, located on Regional Road 81 in the Town of Lincoln. The bridge crosses over Twenty Mile
Creek and is primarily within an area of residential, commercial, and recreational land use. A rehabilitation /
replacement strategy is necessary to address the deteriorating condition of the bridge as identified in the Region’s
Biennial Bridge Inspection Reports.
Opportunity Statement: In order to address the aging infrastructure, Niagara Region is taking the opportunity to
address the structural issues identified and improve overall public safety for auto users, cyclists and pedestrians.
The improvements will also provide an opportunity to achieve the Region’s active transportation objectives by
providing space on the structure for a safe cycling and pedestrian facility.

Alternative Solutions
•    Alternative 1: Do Nothing - Leave the Twenty Mile Creek Arch Bridge on Regional Road 81 in its current
     state. This alternative will result in continuing deterioration of the pre-existing structure and continued two-
     lane operations
•    Alternative 2: Rehabilitation of the Structure - Complete rehabilitation of the existing structure as required
     to maintain vehicular access with minimal disruption to traffic
•    Alternative 3: Replacement of the Structure – New two-lane vehicle bridge using existing or alternative
     roadway alignment

                                                   Most Preferred  Least Preferred
Preliminary Preferred Solution
•    Based on the review of existing and future conditions
     and the assessment of alternative solutions, the project
     team has selected “Alternative 3: Replacement of the
     Structure“ as the Preliminary Preferred Solution
•    Alternative 3 has been identified as the preferred
     solution for the following reasons:
     – It provides an opportunity to improve active
         transportation by providing a wider bridge to
         accommodate active transportation
     – It resolves all structural bridge safety issues and
         meets current regulation standards
     – It complies with rural typology (wide lane widths and
         paved shoulder for cycling) as per Regional policies
     – It has limited immediate maintenance cost
     – It has a longer service life than the rehabilitation
         option (approximately 75 years), which is consistent
         with the recommendations from the Rehabilitation /
         Replacement Planning Report (2010) and biennial
         bridge inspection
•    With proper environmental constraint avoidance and
     mitigation planning, the benefits of the preferred
     alternative outweigh its potential impacts

Limitations
Limitations

1. The work performed in the preparation of this report and the conclusions presented
    are subject to the following:
        a. The Standard Terms and Conditions which form a part of our Professional
            Services Contract;
        b. The Scope of Services;
        c. Time and Budgetary limitations as described in our Contract; and
        d. The Limitations stated herein.
2. No other warranties or representations, either expressed or implied, are made as to
    the professional services provided under the terms of our Contract, or the
    conclusions presented.
3. The conclusions presented in this report were based, in part, on visual observations
    of the Site and attendant structures. Our conclusions cannot and are not extended to
    include those portions of the Site or structures, which are not reasonably available,
    in Wood’s opinion, for direct observation.
4. The environmental conditions at the Site were assessed, within the limitations set
    out above, having due regard for applicable environmental regulations as of the date
    of the inspection. A review of compliance by past owners or occupants of the Site
    with any applicable local, provincial or federal bylaws, orders-in-council, legislative
    enactments and regulations was not performed.
5. The Site history research included obtaining information from third parties and
    employees or agents of the owner. No attempt has been made to verify the accuracy
    of any information provided, unless specifically noted in our report.
6. Where testing was performed, it was carried out in accordance with the terms of our
    contract providing for testing. Other substances, or different quantities of substances
    testing for, may be present on-site and may be revealed by different or other testing
    not provided for in our contract.
7. Because of the limitations referred to above, different environmental conditions from
    those stated in our report may exist. Should such different conditions be
    encountered, Wood must be notified in order that it may determine if modifications to
    the conclusions in the report are necessary.
8. The utilization of Wood’s services during the implementation of any remedial
    measures will allow Wood to observe compliance with the conclusions and
    recommendations contained in the report. Wood’s involvement will also allow for
    changes to be made as necessary to suit field conditions as they are encountered.
9. This report is for the sole use of the party to whom it is addressed unless expressly
    stated otherwise in the report or contract. Any use which any third party makes of
    the report, in whole or the part, or any reliance thereon or decisions made based on
    any information or conclusions in the report is the sole responsibility of such third
    party. Wood accepts no responsibility whatsoever for damages or loss of any nature
    or kind suffered by any such third party as a result of actions taken or not taken or
    decisions made in reliance on the report or anything set out therein.
10. This report is not to be given over to any third party for any purpose whatsoever
    without the written permission of Wood.
11. Provided that the report is still reliable, and less than 12 months old, Wood will issue
    a third-party reliance letter to parties that the client identifies in writing, upon

Project # IM20104013 | May 2021
payment of the then current fee for such letters. All third parties relying on Wood’s
   report, by such reliance agree to be bound by our proposal and Wood’s standard
   reliance letter. Wood’s standard reliance letter indicates that in no event shall Wood
   be liable for any damages, howsoever arising, relating to third-party reliance on
   Wood’s report. No reliance by any party is permitted without such agreement.
