The Study Purpose and Background
Study Purpose

–

The purpose of this Class Environmental Assessment is to identify the preferred
solution to address the deteriorated condition of the Dutch Line Bridge and the Reed
Bridge and prepare a preliminary and detail design for the preferred solution.
Dutch Line Bridge
Study Background
Dutch Line Bridge
•
•
The Dutch Line Bridge is located on Dutch Line Road approximately 2.7 km east
from the intersection of County Road 121 and Dutch Line Road, in the
Municipality of Trent Lakes. The existing bridge was constructed in 1960 and is a
single span structural steel girder bridge with a wooden deck and surface treated
wearing surface that spans Union Creek. The bridge is in poor condition and has
failed in May 2014 prompting full closure of the bridge. The roadway is a single
lane traffic configuration.
The failure of the bridge identified the need for replacement.
Reed Bridge
•
The Reed Bridge is located on Galway Road approximately 2.2 km east from the
intersection of County Road 121 and Galway Road, the Municipality of Trent
Lakes. The existing bridge was constructed in 1950 and is a single span, steel
girder bridge with a wooden deck and surface treated wearing surface that spans
Union Creek. The bridge conveys two-lanes of traffic.
•
A detailed inspection of the structure conducted in 2014 identified settlement in
the west abutment; a subsequent evaluation of the structure resulted in an
immediate need for the structure to be posted for traffic load restrictions and a
need for rehabilitation.

Problem and Opportunity Statement
Dutch Line Bridge

Problem Statement
–
The existing bridge does not meet bridge code requirements and has
deteriorated to a condition such that full closure of Dutch Line Road was
warranted.

Opportunity Statement
–
Replacement / rehabilitation of the Dutch Line Bridge would provide improved
accessibility for residents on Dutch Line Road, and would also provide an
opportunity for a detour route during replacement of the Reed Bridge located
in close proximity to the Dutch Line structure.


Do Nothing
–
This alternative has been included as a basis for comparison to other alternative solutions.

Rehabilitation
–
Rehabilitation of the structure to a functioning state in accordance with current design
standards.

Replacement
–
Replacement of the structure with a new bridge that complies with current design standards
and keeping with the current profile / configuration of the roadway (single-lane). Alternatives
include:




Replacement of the bridge with a pre-cast concrete rigid frame bridge.
Replacement of the bridge with a Super Cor structural steel plate box bridge.
Replacement of the bridge with a steel modular panel bridge.
Corrugated steel multi-plate culvert (closed bottom).

Summary of Evaluation of Alternative Solutions
Dutch Line Bridge

Do Nothing
–
This alternative does not address the existing road closure due to the failure of the structure.

Rehabilitation
–
Rehabilitation of the structure would require major alterations to the existing sub-structure and
deck to comply with current design standards. This alternative solution is not practical given
that the existing structure has already failed.

Replacement
–
Replacement of the structure addresses the problem / opportunity statement by reinstating
traffic access on Dutch Line Road.
–
Replacement alternatives provide a service life range from 50 to 75 years, construction
duration from 4-8 weeks, and construction cost from approximately $675,000 to $810,000.
Addendum: For a single lane replacement structure, the replacement construction cost will be
approximately $480,000 to $595,000).

Preliminary Recommended Solution
Dutch Line Bridge – Replacement with Pre-Cast Concrete Rigid Frame Bridge
Criteria / Rationale:

Replacement design to similar dimensions and opening of the existing bridge thereby
minimizing extent of impacts during construction.

Existing roadway width (single lane traffic configuration) to be maintained given the
low average annual daily traffic (AADT) volumes on Dutch Line Road.

Existing roadway profile of Dutch Line is proposed to be raised to accommodate
existing drainage concerns.

Longest structural service life (estimated to be 75 years) of structural alternatives.

Reasonable construction duration (6-8 weeks).

Reasonable construction cost ($725,000; Addendum: For a single lane replacement
structure: $530,000).

Culvert design not feasible due to poor subsoil founding conditions.

Problem and Opportunity Statement
Reed Bridge

Problem Statement
–
The existing bridge does not meet bridge code requirements and has
deteriorated to poor condition including severe rot of the timber curbs and
deck soffit, corrosion of girders, settlement of the west timber crib (abutment)
and the need for the structure to be posted for traffic load restrictions and
frequent inspection (minimum of 6 month frequency).

Opportunity Statement
–
Replacement / rehabilitation of the Reed Bridge will provide improved safety
conditions on Galway Road for the crossing of Union Creek given the
deteriorated condition of the structure.

Summary of Evaluation of Alternative Solutions
Reed Bridge

Do Nothing
–
This alternative does not address the deteriorated condition of the structure. This alternative
will lead to additional deterioration of the structure leading to increased costs for repairs /
rehabilitation.

Rehabilitation
–
Rehabilitation of the structure would require major alterations to the existing sub-structure and
deck to comply with current design standards. Geotechnical investigation at this site has
indicated the need for the structure to be founded on piles driven to bedrock. Significant cost
would be incurred to rehabilitate the structure to current design standards.

Replacement
–
Replacement of the structure addresses the problem / opportunity statement and would be a
cost-effective long term strategy given the current deteriorated state of the structure.
–
Replacement alternatives provide a service life range from 50 to 75 years, construction
duration from 4 to 8 weeks, and construction costs from approximately $675,000 to $760,000.

Summary
Conclusions:



The existing Dutch Line Bridge and Reed Bridge
have deteriorated and do not meet bridge code
requirements. The Dutch Line Bridge is currently
closed to all traffic.
Alternative solutions reviewed for each structure
included Do Nothing, Rehabilitation, and
Replacement (alternatives pre-cast concrete rigid
frame bridge, Super Cor structural steel plate box
bridge, Steel Modular Panel bridge, and corrugated
steel multi-plate culvert).
Preliminary recommended solutions for each
structure include replacement with a pre-cast
concrete rigid frame bridge. This option provides a
reasonable construction duration, the optimum /
reasonable construction cost, and the longest
structural service life of all alternatives.
Next Steps
Upon completion of the Public Information Centre, the
following steps will be taken:

Review comments received from the Public/Agencies
for consideration in finalizing the preliminary design.

Review the preferred alternative design concept in
consideration of public / agency comments.

Further review the preferred alternative design concept
in consideration of natural, socio-economic, cultural,
and transportation environments.

Confirm the preferred alternative.
