What type of grade-separated crossings are being considered?
Any future expansion of Lemay Avenue, Timberline Drive, and Mountain Vista Drive would not be permitted as at-grade crossings by the BNSF Railroad Company. The type of crossing (overpass or underpass) would be identified as development occurs or as street widening is warranted. This analysis would not only study the cost of both types of crossings, but also the visual, noise, and economic impacts. The preliminary cost estimate for all three grade separated crossings is $51 million. This figure does not differentiate between an underpass and an overpass. Refined numbers will be prepared as part of the planning process.
