The project is ahead of schedule and will be completed mid May. The contractor is installing the curb and will be starting to pave next week. On Monday, May 1st (weather dependent), lane restrictions at the intersection of Talbot Street and First Avenue will be in place from 9pm until 7:30am the next morning to complete the paving of the intersection. Westbound traffic on Talbot will be able to turn northbound onto First Avenue, Eastbound traffic on Talbot will be able to turn northbound onto First Avenue, and Southbound traffic on First Avenue will be able to turn westbound onto Talbot Street, all other movements will be restricted.
Road Construction FAQ
How Does the City Choose Which Streets to Reconstruct?
When looking at a street people can only see what is on the surface including the road, sidewalk, and curb and gutter. However, if we look further, there is a lot of important but often unnoticed underground infrastructure including sewers, watermain, gas, electricity, etc.
Choosing when to reconstruct a street involves analyzing each piece of infrastructure within a roadway and determining the most effective year to complete the work. In an ideal situation all of the infrastructure would require replacement at the same time, but in reality the lifecycle of each piece varies (i.e. local road - 40 years, watermain 75 years, sewer - 100 years). Each piece of infrastructure is inspected on a regular basis and given an overall rating. Streets are then prioritized on criteria related to each of the individual pieces of infrastructure including condition, target level of service and risk.
It can be challenging to prioritize which street to reconstruct. In addition to the items mentioned there are other factors that might prioritize one street over another including if it has combined sewers (where storm flows enter the sanitary sewer) or increased capacity is required for upstream development.
An example of the decision that needs to be made is: do you reconstruct the street where the road is in good condition but the sewers are in very poor condition or the street where the road is in fair condition and the watermain is in poor condition?
This decision is similar to that of a homeowner who has to weigh the pros and cons of various projects and prioritize what work can be completed within their budget. For example, do you replace your leaky roof or your old furnace which will break at any moment?
How many roads are there, what are they worth and how much should we be replacing each year?
The city has 437 lane kilometers of road (1 kilometer of 4 lane road = 4 lane kilometers) with an estimated replacement value of $274 million. For a fully sustainable road network we should be spending between $5.5 million and $8.2 million per year on our roads. For more information see the roads asset report card.
Was there an abnormal amount of roadwork in 2016?
Yes. 2016 was the largest capital program in St. Thomas history. An early tending process and supportive Council allowed for a significant number of projects to start early in the year and be finished by July. A large number of backlogged projects were completed. Also, the road rehabilitation style that was tendered allowed for a great value in terms of dollars spent versus the number of roads rebuilt.
Why is the city constructing this street, when another street appears to be in worse condition?
The City has a long term asset management plan that prioritizes which street to reconstruct based on a large set of criteria. This means that sometimes a road is reconstructed where the surface appears to be in better condition than another street for a number of reasons:
- a preventative rehabilitation provides best value
- the underground infrastructure is in worse condition
- there is a higher environmental or social risk of infrastructure failing
- the work is coordinated with other replacement work
- the other street in question is scheduled for a future reconstruction
- the upstream area requires larger sewers/water for a new development or redevelopment
Why have I seen streets repaved numerous times when my street has never been repaved?
Different types of streets have different levels of service. For example, arterial roads like Talbot Street are given higher priority as they have more traffic and higher pedestrian volumes compared to local roads. These roads require more attention as the asphalt surface wears quicker and vehicles travel at higher rates of speed.
Does the City use new technology or unique construction methods to save money?
For each project the City evaluates and determines the most cost effective method to complete the work. If only one or two pieces of underground infrastructure are in poor condition but the others are in good condition and the surface is in good condition then trenchless technologies are evaluated. Trenchless construction means that the road is not ripped up to complete the work. For sewers, the work can be completed from the manholes. For watermains, only a few small excavations are required. Trenchless options can provide significant cost savings compared to full reconstruction and minimize the disruption to the street.
Why do some projects only replace part of the asphalt and others replace all of the asphalt?
If the underground infrastructure is in good condition and only the asphalt is in poor condition then we do a road rehabilitation where typically only the asphalt is removed and replaced. When choosing which rehabilitation technique to use we try to match up the future reconstruction requirements. Removing and replacing only the top half of the asphalt can add 10-20 years to the life of the road and replacing all of the asphalt can add 30-40 years to the life. If the underground infrastructure needs to be replaced in 20 years then we wouldn't want to spend the extra money for the 30-40 year fix right now.

Why can't construction be done at night or 24/7 to get the project complete quicker?
The City reviews each individual project for options to get them completed as quickly as possible. Construction contracts have deadlines that must be met and financial penalties if they are not met. Schedules are set based on the concept of forcing the contractor to work as quickly as possible but not too fast to drive up the cost.
Overnight construction increases costs, increases safety risks, and results in noise concerns both at the construction site and along trucking routes. Contractors already work long days and for most projects overnight work is not appropriate. However, overnight work can be an option for high disruption, short term construction, for example when repaving a major intersection.
So work can be done at night but adds increased costs. Higher cost projects either lead to less projects being completed overall or higher taxes. A balance needs to be found between mitigating social impacts and affordably replacing our infrastructure.
Please be advised that construction will start on Elm Street from Centennial Avenue to east of Tyke Road for underground storm sewer installation. The construction will start on Monday, May 1, 2017 with traffic control and lane restriction in place until the end of May 2017. Please follow traffic control signs and personnel on site in order to navigate through the construction zone safely.
The City is excited to announce the Edward Street Road Rehabilitation Project will start in April. The Burwell Road Rehabilitation project will begin after Edward Street has been completed. Construction is expected to be complete in July 2017. For more information visit the Construction Projects page.
The Elgin St. Thomas Age-Friendly Committee is developing a community plan for residents of Elgin County and the City of St. Thomas. An Age-Friendly community is one where policies, services and structures related to the physical and social environments support and enable older residents to lead healthy, active lives and stay involved in their communities.
