Blue Line Should Branch from Orange Line Urban Rail — Nix the Redundant Infrastructure!

15 August 2019

Map shows ARN’s alternative proposed urban rail configuration in Core Area connecting Orange Line (Tech Ridge to Slaughter Lane) with Blue Line (UT campus through Core Area and East Riverside to ABIA). Both lines would share First St. (Drake) Bridge over river, thus eliminating need for an expensive redundant Blue Line bridge. Blue Line would branch from Orange Line at Dean Keaton and at W. 4th St. to serve east side of Core Area and provide link to airport. Map: ARN.

► Orange Line as primary corridor — Urban rail installation in the Orange Line alignment (N. Lamar-Guadalupe-Lamar-South Congress/NL-G-SC) must be prioritized. Positioned as Austin’s major central local corridor, between I-35 to the east and Loop 1 (MoPac) to the west, the Orange Line corridor is the center city’s 3rd-heaviest north-south travel corridor (after I-35 and MoPac). The City of Austin has repeatedly emphasized that this is the primary local traffic corridor in central-city Austin, with exceptionally heavy traffic at maximum capacity for over the past 2 decades. North Lamar alone is ranked by Texas Transportation Institute as one of the most congested arterials in Texas. With Austin’s highest total employment density on Guadalupe-Lamar, an urban rail line there alone could serve 31% of all Austin jobs. It would also serve the highest-density residential concentrations in the city — including the West Campus, ranking the 3rd-highest in residential neighborhood density among major Texas cities.

► Light rail transit (LRT) — For over 30 years, urban rail in the NL-G-SC (currently designated Orange Line) alignment has been regarded as the key central spine for an eventual citywide and regional urban rail network using well-proven, widely deployed, effective, affordable light rail transit (LRT) technology. Particularly with little to no need for major civil works, the Orange Line is ideal for a surface-installed LRT starter line.

Since initially selected as Capital Metro’s Locally Preferred Alternative in 1989, LRT has remained Austin’s premier major high-capacity transit vision. LRT has demonstrated numerous key advantages over bus rapid transit (BRT). And unlike many “gadget” alternatives, LRT is well-proven in service, a readily available technology, and non-proprietary. (In contrast, “autonomous BRT” has been neither deployed commercially nor even tested.) Compared with buses, LRT systems provide higher capacity and are faster, more user-friendly and more comfortable to access and ride. On average, ridership on new LRT systems is 127% higher than on BRT. LRT is also more cost-effective – average operating cost of new LRT systems is 10% lower than for BRT.

► Alternate Blue Line — Simply trying to resurrect the failed 2014 Highland-Riverside plan is not a prudent option. The Blue Line makes the most sense if it shares segments of the Orange Line, branching from it to serve the eastside of the Core Area and UT, and the East Riverside corridor (and ultimately ABIA). Running westward from ABIA on East Riverside, the Blue Line in this proposal would join the Orange Line south of the S.1st St. (Drake) Bridge. Sharing trackage across the bridge, it would proceed northward to Republic Square, where it would turn east to the San Jacinto/Trinity arterial pair, then turn northward and proceed to serve the Medical District and the UT East Campus. At Dean Keaton, the alignment would then turn west and travel on Dean Keaton toward Guadalupe St. to rejoin the Orange Line, proceeding northward from there. Access to-from ACC Highland could be made available via transfer with Red Line trains (with improved frequency) or various bus alternatives (from UT campus or Crestview).

► Eliminate redundant infrastructure — Major advantages of this alternative include more efficient operation, better passenger interconnection between Blue and Orange Lines, and very significant cost savings through eliminating redundancy: the proposed bridge over the Colorado, approximately three miles of line infrastructure paralleling the Orange Line, and five stations.
