Construction Projects

Oxford County is beginning a multi-year reconstruction project to improve Devonshire Avenue in Woodstock. This year’s work is expected to begin mid-April and will be completed in two parts. 

April – August 2025 - Complete

Vansittart Avenue/Devonshire Avenue intersection: Oxford Road 59 bridge to Vincent Street

• Vansittart Ave from Vincent St to Tecumseh St will be closed to southbound traffic. Two detour routes will be in place at Oxford Road 17: Detour 1 west to Oxford Road 30/11th Line, Detour 2 east to Oxford Road 4
• Tecumseh Street will remain open to local traffic only

April – December 2025 - Complete

Devonshire Avenue: Vansittart Avenue to Victoria Street North

• Devonshire Ave from Vansittart Ave to Victoria St will be closed to through traffic in both directions
• A detour route will be in place using Oxford Road 59 (Vansittart Ave), Ingersoll Ave and Huron St

Work includes sanitary, storm and watermain replacement and repairs; road replacement with a three-lane cross section; bike lanes and sidewalks; and traffic signal and street light replacement.

Future phases will include a different section of Devonshire Avenue each year, extending east to Oxford Road 4, excluding the area between Lansdowne Avenue and Woodall Way. This final phase of the project is expected to finish in 2028.

Please note, construction schedules are weather dependent and subject to change based on contractor availability and other operational demands.

A section of the City of Woodstock’s Standard Tube, Burgess, and Rotary Club Millennium Trail along Oxford Road 30 (11th Line) is closed for work by Oxford County due to erosion between the roadway and trail.

To stabilize the slope and prevent further erosion, design of a retaining wall and further embankment stabilization began in fall of 2024 with construction expected in 2026. This section of trail will remain closed until construction is complete.

To prepare for construction on the slope, Oxford County retained a tree clearing contractor to remove trees located within the slope failure area on Oxford Road 30. Tree clearing work was completed by March 31, 2025, to comply with requirements of the Migratory Bird Convention Act. In accordance with the City of Woodstock’s Tree Management Guidelines and upon completion of the slope work, roughly half of the removed trees will be replaced at a 3:1 ratio to support environmental sustainability. This work is essential to ensure safety and prevent further soil erosion in the area.

Lansdowne Avenue (Township Road 3) will be closed from Halifax Road to Oxford Road 4, beginning late June until the end of August 2025 for sanitary sewer construction in support of the new pumping station under construction at 1074 Lansdowne Avenue. The work includes removing and replacing existing road makeup, ditch re-alignment, and improvements to local storm drainage.

Traffic will be limited to local residents, businesses and emergency services. A detour route will be in place for the duration of construction.

Detour: Lansdowne Avenue (Township Road 3), Devonshire Avenue (Oxford Road 35) and Oxford Road 4.

Construction of the sanitary pumping station began in January 2025 and is expected to be completed in March 2026.

Construction schedules are weather dependent and subject to change based on contractor availability and other operational demands.

Oxford County will begin work to install a backup generator at Wellhouses 4 and 5, located at 164164 Brownsville Road west of Tillsonburg, in September 2025. The two wellhouses are part of a critical network of 12 that supply drinking water to the Tillsonburg area.

The new back-up generator will help ensure Tillsonburg’s supply and demand needs for water can continue to be met as it experiences rapid growth. The project is scheduled for completion by December 2025.

Construction of a new on-site water treatment facility at 445 Broadway Street is tentatively scheduled to begin early November 2025. The work includes demolition of the existing facility at 451 Broadway Street and site servicing improvements including watermain, sanitary sewer and storm sewer. This project is essential for enhancing the community’s water infrastructure, improving water quality, and ensuring long-term sustainability of the drinking water supply system.

Broadway Street will remain open to traffic during construction. Work will be limited to 445 and 451 Broadway Street, with access to the construction site maintained through the existing entrance on Christie Street.

Construction of the Well 7A water treatment facility is expected to be completed by December 2026. Construction schedules are weather dependent and subject to change based on contractor availability and other operational demands.

Update: Questions about arsenic removal process

Oxford County has received questions about the project's description on posted signage as an arsenic treatment project. Please be assured that drinking water in Tillsonburg remains safe and well within all provincial water quality standards. There is no risk to public health, and residents should continue to use their tap water as normal.

The Well 7A project is designed to bring a number of improvements to water treatment processes, including the installation of a dedicated filter to remove naturally occurring arsenic on site. This allows water to be supplied from this well independently to the Fairview treatment plant in future. Together, the improvements being made at the well will increase the amount of safe drinking water available to the community as a whole.

Oxford Road 9 (Hamilton Road/King Street West), from CPKC Railway west to the Town of Ingersoll boundary and the intersection of Oxford Roads 9 and 10 (Ingersoll Street South), is expected to be closed to through traffic beginning in April 2026 (to be confirmed) for infrastructure improvements. Construction will include relocating utilities; replacing sanitary sewer, watermain, curb and gutter; new traffic signals at Oxford Roads 9 and 10 and new street lighting; storm sewer improvements; sidewalk upgrades; and landscaping and restoration.

Sections of the Lawson Park trail will be closed beginning in January 2026 and are expected to reopen when construction is complete (see map below).

Construction will be carried out in two phases:

• Phase 1 – November 2025 to April 2026: Sanitary sewer installation by micro tunnel from a compound area south of Lawson Trail and northeast of the intersection of Oxford Road 9 and Oxford Road 10
• Phase 2 – April to December 2026: Sanitary, watermain and storm sewer; full road reconstruction; traffic signals; and final surface (asphalt) treatments

During Phase 2, Oxford Road 9 will be closed to through traffic. Traffic will be limited to local residents, businesses and emergency services. There will be a planned detour route in place for the duration of the road closure including applicable detour signage:

Detour: Elgin Road, Road 60 and Oxford Road 10 (Ingersoll Street North)

Please note that additional local detours routes may be in place at set periods during construction.

Road work is expected to be completed by December 2026. Please note, construction schedules are weather dependent and subject to change based on contractor availability and other factors.
