Report Number: ENG 01-21
Date: January 4, 2021
From: Richard Holborn
Director, Engineering Services
Subject: Municipal Bridge Maximum Gross Vehicle Weight Restrictions
- By-law to establish a load limit for certain bridges under the jurisdiction of the City
of Pickering
- File: A-1440
Recommendation:
1. That the attached draft By-law limiting the gross vehicle weight of any vehicle or any class
thereof, passing over certain bridges, under the jurisdiction of The Corporation of the City of
Pickering be enacted; and,
2. That the appropriate officials of the City of Pickering be authorized to take the necessary
actions as indicated in this report.
Executive Summary: The Highway Traffic Act and Ontario Regulation 104/97 Standards for
Bridges require that every bridge and/or structure be kept safe and in good repair through periodic
inspections under the direction of a Professional Engineer and in accordance with the provisions
of the Ontario Structure Inspection Manual, or equivalent. Further, The Highway Traffic Act
establishes that municipalities having jurisdiction over a bridge may by by-law limit the gross
vehicle weight of any vehicle or any class thereof passing over the bridge. The City of Pickering
retains a qualified bridge inspection firm to perform regular bridge inspections every 2 years.
In 2018, the City of Pickering retained Keystone Bridge Management Corporation to inspect and
validate the gross vehicle weight limit restrictions for the bridge structures included in the parent
by-law. Keystone Bridge Management Corporation conducted bridge load testing on 7 municipal
bridges in support of determining the appropriate load limit for by-law purposes. As a result of the
testing, load limits were assigned to the 7 bridges and established through By-law 7674/19 and
accompanying Schedules A and B.
Keystone Bridge Management Corporation was retained in 2020 to assess the City’s 71 bridges
and culverts, of which 55 have a span of 3.0m or over. As a result of the recent assessments and
inspections, 3 additional bridges require a load limit by-law and 1 bridge with an existing load limit
by-law requires the load limit to be reduced, with a “Use at Own Risk” signage. Bridge #1002 on
the Uxbridge Pickering Townline Road is currently being replaced, therefore a load limit will no
longer be required.
Based on the above, staff have prepared a proposed by-law which identifies the new
recommended maximum weight load limits on 4 bridges (Bridge #7004, 8004, 8007 and 9003),
ENG 01-21 January 4, 2021
Subject: Municipal Bridge Maximum Gross Vehicle Weight Restrictions
By-law to establish a load limit for certain bridges under the
jurisdiction of the City of Pickering Page 2
maintains the existing maximum weight load limits on 5 bridges (Bridge #6003, 7002, 8001, 8003,
9006), and repeals the previously established associated by-law By-law 7674/19.
Financial Implications: The cost for Keystone Bridge Management Corporation to inspect and
re-affirm proposed load limits at the 9 bridge locations and to certify the by-law was $4,725.00
plus HST which is being charged to 2290.2392.0000 Engineering Services – Administration. In
order to remove the bridge load limits, future expenditures will be required to rectify structural
deficiencies and to bring the bridges up to current code requirements.
Discussion: In January of 2019, staff presented report ENG 01-19 to the Executive
Committee. The report, as adopted by the Committee and approved by Council:
• identified the maximum vehicle load limits established on 7 bridges as a result of the
inspections on all bridges currently under the jurisdiction of the City of Pickering;
• presented for Council endorsement, the draft by-law necessary for bridge load
designations; and,
• established the necessary schedules for signature by 2 Professional Engineers certifying
the safe load limits and the duration for which the limits apply.
As a result of the inspections undertaken by Keystone Bridge Management Corporation in 2020,
there is a need to reduce the maximum vehicular weight limit restriction of Bridge #7004 (Sideline
34 - 0.2km south of Eighth Concession Road), from 10 tonnes to 5 tonnes which was the
cautionary load limit as set out in Municipal Bridge Load By-law 7674/19. Three additional bridges:
Bridge #8004 (Lot 20/21 Conc 8); Bridge #8007 (Lot 12/13 Conc 8); and Bridge #9003 (Lot 28/29
Conc 9) require a load limit by-law. Bridge #10002 on Uxbridge Pickering Townline Road 0.10 km
east of Sideline 30 is currently under construction and no longer requires a load limit.
The maximum vehicular weight limit restriction for the remaining 5 bridges remains the same as
set out in the current by-law (By-law 7674/19).
A copy of bridge site location maps, the draft amending by-law and revised Schedule “A”, which
identifies all structures to which the by-law applies, are attached.
If passed by Council, a completed Schedule “B” will be signed and sealed by 2 Professional
Engineers from Keystone Bridge Management Corporation and will form part of the new by-law.
