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.
