In our Feb. 10th article «Long saga of Guadalupe-Lamar light rail planning told in maps» we provided a selective summary chronicle of the exhaustive history of planning for major infrastructure upgrades — almost all of it light rail transit (LRT) — to expand capacity, enhance urban livability and the environment, and improve and sustain mobility in Austin’s most important central local corridor, Guadalupe-Lamar (G-L). Over 40 years of LRT proposals and studies were noted and maps associated with them were presented, among them several alternatives we’ve featured on this website.

As we’ve contended in our article «Strong community support for Guadalupe-Lamar light rail continues — but officials seem oblivious», there’s abundant evidence of enduring community interest in, and support for, LRT in this crucial corridor, indicated in part by various alternative route proposals that have emerged in recent years. One of these — originally presented in a posting on this website last October as a so-called “Plan B” proposal (the name deriving from the presumption that the disastrously flawed officially sponsored Highland-Riverside urban rail plan, decisively rejected by voters in November, was “Plan A”) — has been modestly developed as a light rail transit (LRT) starter line project with suggested basic planning, route, and design concepts:

So, on the assumption that the critical mass of community and political support could be mustered to proceed, how long would it take to get an actual G-L starter line (the seminal “spine” from which extensions throughout the metro area and the region would subsequently branch) in operation? What milestones might there be along the way, and what might be typical (or at least realistic) timeframes for achieving each milestone? And could a new Project Connect-style study be initiated and concluded within about a year, in time to put a rail project funding measure on the ballot in 2016?

In response to these issues, we’re posting here a somewhat fanciful and speculative timeline (based on the proposed 6.8-mile G-L-Seaholm line described in our “Plan B” article cited above), with some modestly rosy assumptions, but based on real-world experience elsewhere. In addition, it’s been vetted by a number of transit industry professionals and savvy advocates.

Our timeline assumes that some project phases could be accelerated or “telescoped” because so much previous study and analytical work has already been completed on this corridor (and some of the planning work involved in the Highland-Riverside proposal might also be applicable). Obviously, all dates (and phases) should be considered as hypothetical, and thus to have some room for adjustment.

This information is mainly intended just to provide a general idea of a possible timeline for such a project in the G-L corridor. Typically, project timelines are meticulously developed by an entire project team and are subject to ongoing revisions.

As our timeline suggests, it’s plausible to envision that a G-L LRT starter line project could be completed within about seven years from the start of conceptual system-level planning. This would lead to a possible opening of the line for service in 2022. To meet such a schedule, system-level planning (to develop a basic conceptual plan to present to the public and to voters for funding) would need to begin sometime later this year — ideally, in the early to middle autumn. Otherwise it would be difficult to finalize a plan for a public vote by November 2016.

Missing the Nov. 2016 vote deadline, as we understand current state law governing bond elections, would likely introduce two more years of delay. This would push a hypothetical vote to 2018, and service startup to the year 2024. In any event, it’s clear that a plausible case can be made that urban rail, in the form of surface LRT, could be up and running in the Guadalupe-Lamar corridor within a decade, and quite likely sooner. ■
