Cyrville Road Bridge Replacement at Highway 417 (Ottawa Queensway)

Detail Design StudyGroup Work Project 4011-06-00

Page 2

Study Purpose•Carry out a Detail Design and Class Environmental Assessment (EA) Study to facilitate the replacement of Cyrville Road Bridge.

•Document the Study in a Transportation Environmental Study Report (TESR).

•Prepare a Construction Contract for the recommended Bridge improvements.

Study Background

• Planning, Preliminary Design and Transportation Environmental Assessment study undertaken to determine long-term operational improvements along Highway 417 (Ottawa Queensway) from Highway 416 Easterly to Anderson Road (GWP 663-93-00), which included the Cyrville Road Bridge replacement.

• Completed TESR and Preliminary Design Report for the Highway 417 operational improvements in 2007.

• Environmental approval obtained in October 2008.

• Identified need to replace Cyrville Road Bridge in advance of scheduled Highway 417 operational improvements to address existing structural deficiencies associated with the age of the bridge.

• Initiated current detail design study to facilitate replacement of the Cyrville Road Bridge.

Alternatives to the Undertaking

Alternative 1: Do Nothing

Alternative 2: Rehabilitate Bridge

Alternative 3: Remove Bridge

Alternative 4: Replace Bridge with existing two lane width on Cyrville Road with provisions for future widening of Cyrville Road

Alternative 5: Replace Bridge with widened four lane width on Cyrville Road to accommodate future expansion of Cyrville Road

Page 8

Preferred Alternative

Rationale In Support of Carrying Forward

•Addresses deteriorated condition of the bridge.

•Supports future operational improvements on Highway 417 and Cyrville Road (i.e., sufficient span length and bridge deck width respectively).

•No future traffic and community impacts associated with four lane widening of bridge.

•More cost effective for City of Ottawa than implementing four lane widening at a later date to accommodate the future expansion of Cyrville Road.

Alternative 5:

Carried Forward

Replace Bridge with widened four lane width on Cyrville Road to accommodate future expansion of Cyrville Road

Construction Staging Alternatives

Alternative 5a

Preferred

Reconstruction of the Cyrville Road Bridge in one stage with localized full closure of Cyrville Road at Highway 417 during construction.

Alternative 5b

Not Preferred

Reconstruction of the Cyrville Road Bridge in two stages to maintain traffic on at least one alternating single lane with temporary traffic control signals during construction.

Alternative 5c

Not Feasible

Rapid Replacement Technology – includes building the bridge in a staging area and moving it into place upon completion with a series of short term closures.

• Not feasible due to the lack of a suitable staging area in close proximity to the bridge site required to construct the new bridge.

• Long term full closure of Cyrville Road is still required to construct pier and abutments for increased three-span bridge arrangement.

Page 10

Preferred Staging Alternative

Rationale In Support of Full Closure

•Minimize cumulative traffic impacts on Cyrville Road and adjacent roadways over the duration of construction (1 year full closure impact vs. 2 year staged construction impact).

•Improve safety for construction workers and motorists by eliminating traffic through a confined work zone and southbound sightline restrictions to Labrie Avenue.

•Improve construction efficiency and reduce overall construction duration (1 yr. vs. 2 yrs).

•Reduce combined construction and contract administration costs ($16.05 vs. $21.3 M).

•Coordinate timing of construction with future operational and safety improvements on Highway 417 scheduled to commence in 2012 (subject to funding and environmental approvals).

Alternative 5a:

Preferred

Reconstruction of the Cyrville Road Bridge in one stage with localized full closure of Cyrville Road at Highway 417 during construction.

Rapid Bridge Removal and Demolition

• Benefits include reduced construction schedule, cost savings and minimal disruption to Highway 417 traffic.

• Contractor will be responsible for preparing a Removal and Demolition Plan detailing a step-by-step procedure that addresses all aspects of the structure removal and demolition.

• Measures need to address the proximity to and protection of the City of Ottawa watermain located in front of the Cyrville Road Bridge south abutment below the existing Highway 417 outside eastbound lane.

• Financial penalties will be imposed for delays in re-opening all lanes of Highway 417 traffic.

Compatibility with Future Planning Initiatives

MTO Highway 417 Improvements

• Construction timing compatible with Highway 417 improvements scheduled to commence as per Southern Ontario Highways Program.

• Span lengths accommodate proposed future Highway 417 widening.

• Third span accommodates independent Ottawa Road174 to St. Laurent Blvd. ramp.

Interprovincial Crossing Study

• Bridge span arrangement will not preclude incorporation of Aviation Parkway interchange modifications.

• Third span adaptable to permit proposed Aviation Parkway ramp configuration.

Downtown Ottawa Transit Tunnel

• Construction timing to be coordinated with DOTT improvements scheduled to commence in 2011.

• Bridge general arrangement and substructure compatible with DOTT improvements.

Page 15

Cyrville Road Operational Improvements

• Bridge cross-section will accommodate two lanes of traffic, bike lane and sidewalk in both directions including provisions for median island.

Ottawa Road 174 Operational Improvements

• Construction timing compatible with Ottawa Road 174 improvements schedule for completion in 2010.

• Outside limits of proposed improvements.
