LEFT: Denver’s starter LRT line, a 5.3-mile line opened in 1994, was routed and designed as a simple, surface-routed project to minimize construction time and cost. All-surface alignment avoided heavy, expensive civil works and kept design as simple as possible. Photo: Peter Ehrlich. RIGHT: Subsequent extensions, such as this West line opened in 2013, have required bridges, grade separations, and other major civil works, resulting in a unit cost 61% higher than that of the starter line.

Since Project Connect released the cost estimates for their proposed 9.5-mile Highland-Riverside urban rail starter line last spring, agency representatives have tried to argue that the line’s projected cost of $144.8 per mile (2020 dollars) is comparable to that of other recent light rail transit (LRT) projects, citing new extensions in Houston, Portland, and Minneapolis.
