Document Description
The Bastanchury Road Improvement Project proposes to improve a segment of Bastanchury Road between Eureka Avenue and Casa Loma Avenue by raising the road profile a maximum of approximately six feet, widening the roadway segment from two travel lanes (one travel lane in each direction) to a total of four travel lanes (two lanes of travel in each direction) to match the existing roadway configuration east of Eureka Avenue and west of Casa Loma Avenue. Additionally, the proposed would improve the current deficient stopping sight distance for motorists traveling on along Bastanchury Road within the project limits, improving safety. The project proposes to install traffic signals at the intersections of Bastanchury Road/Eureka Avenue and Bastanchury Road/Casa Loma Avenue, and would include a left turn lane at each intersection along Bastanchury Road. To accommodate planned development located on a vacant parcel north of the project site, a driveway would be installed along with an eastbound left turn lane to provide future access to the site. Sidewalk would be installed north of the westbound travel lanes. A 10-foot wide Class 1 multi-purpose trail and an approximately 10-foot high retaining/property wall (seven feet expo~ed) would be installed south of the eastbound travel. lanes.
