Road work shortened by soil contamination
Although a near 500-metre stretch of County Road 18 in Martintown will undergo reconstruction work next week, the United Counties of Stormont-Dundas-Glengarry say the work could have been a lot more extensive had it not been for the presence of soil contamination.
At its Aug. 21 meeting, counties council elected to follow a staff recommendation to rebuild the road from the Nine Mile Road to the bridge in the middle of Martintown. The original project would have extended to McMartin Street and even beyond, but the state of the soil, as well as budgetary constraints, prompted council to approve the abbreviated work project.
“One of the significant project challenges discovered during the design phase was that there was soil contamination near the intersection of CR 18 and CR 20,” wrote Counties Engineer Benjamin de Haan in his staff recommendation. “Staff have contacted the Ministry of Environment and completed hydrocarbon testing concurrent with the geotechnical assessment completed for the site. This analysis confirmed that there were hydrocarbons present in the right of way.”
The construction project includes replacing asphalt, bases and subbases, and installing new maintenance holes and storm sewers. If such work were to take place east of the bridge, construction workers would have encountered the contaminated soil. According to Mr. de Haan's report, doing so would have either greatly increased the project's cost or would have required that the new road construction project be redisturbed at a later date. As such, council elected to allow the Ministry of the Environment and the Technical Standards Safety Association to work with the landowner to remediate the contaminated soil.
The construction project is slated to begin Sept. 11 and will likely be completed by the end of October. Motorists are warned that there will be delays on that road and that traffic will be reduced to one lane.
The initial cost of the project was just under $1.2 million but after removing the work east of the bridge, the price tag falls to about $650,000. The project will be undertaken by Malyon Excavation Ltd.
