2.0 BACRGRODND
2.1 Due to the obsolescence or weakening of bridges, it is often
necessary to limit the gross weight. of vehicles on highways or
bridges on a temporary, seasonal or more permanent basis.
Subsection 104 b(2) of the Highway Traffic Act. (R.S.O. 1980,
c.198 as amended) provides that:
"The municipal corporation or other authority
having jurisdiction over a bridge may by by-
law approved by the Ministry limit the gross
weight of any vehicle or any class thereof
passing over such bridge, and the requirements
of subsection (1) with respect. to the posting
of notice apply. thereto."
3.0 REVIEW AND COMMENT
3.1 Although all municipal bridges having a rating of 10 tonnes or
less have been posted with maximum weight signs for a number
of years, no valid by-law exists to permit enforcement. The
Ministry of Transportation will only approve such by-laws if
they are supported by an engineering bridge appraisal study.
The Ministry will approve the by-law with a specific expiry
date which ensures that bridge inspections will occur every
few years to update the by-laws.
3.2 The firm of Totten Sims Hubicki and Associates prepared the
Municipality of Clarington 1993 Road Needs Study Update. with
respect to bridge appraisals using a Ministry approved
computer software package named MBADES. The bridge appraisals
binder, providing details on all Municipal bridges, was
submitted to the Municipality during March of 1994. Upon
reviewing the bridge appraisals, it was noted that a number of
~~~ 7
REPORT NO.: WD-51-94 PAGE 3
signing changes must occur and, in the interest of public
safety, those signs. have been placed on order in advance of
-this report being submitted to Council. .The Manual of Uniform
Traffic Control Devices illustrates the two (2) available sign
styles as shown on Attachment No. 3. The (RB-63) signs are
used where the maximum gross weight applies to single and
combination vehicles. The (RB-63A) signs are used where
structural engineers have set individual load restrictions
prescribing the maximum gross vehicle weight for a single
vehicle, a combination of two vehicles and a combination of
three vehicles permitted on the bridge.
3.3 The engineering recommendations included the posting of
maximum weight signs for twelve (12) structures. The Bridge
Appraisals to support the recommendations and By-law are
available in the Public Works Department.
4.0 CONCLUSIONS
4.1 From the above, it is concluded that the attached By-law
should be approved by Council and forwarded with the Bridge
Appraisals to the Ministry of Transportation for their
consideration and approval.
Respectfully submitted,

a) in the case of a single vehicle, or where the same
maximum gross weight applies to single and combination
vehicles, the gross weight exceeds the number of tonnes
set out in Column 3 (a);
b) is the case of a combination of two (2) vehicles, the
gross weight exceeds the number of tonnes set out in
Column 3 (b); and
c) in the case of a combination of three (3) vehicles, the

capacity.
It shall be located in advance of a bridge or other struc-
ture to which the restriction applies. It may also be
