Wabaseemoong Independent Nations – Access Road Improvement


Details

Background

TBT Engineering was retained by Wabaseemoong Independent Nations to provide professional engineering services for the investigation and design portions of proposed road work to upgrade the existing White Dog Community roadway system and the Hwy access road. A total of 15.8 km of the existing unsurfaced, granular/dirt roadway was improved by providing grading enhancement and surfacing of the roadway. The purpose of the project was to increase the level of service to the Community by improving the access roadway in a cost effective and timely manner. Improving the road base, ensuring adequate drainage, and re-surfacing of the route allowed for improved road access, rideability, driver safety, and reduced overall maintenance costs for the Community.
