Phase 2B of the Foothill Gold Line Light Rail Program
Hill International announced that design is nearing substantial completion for the baseline Phase 2B of the Metro Gold Line Foothill Extension Construction Authority’s Gold Line Light Rail Program, and construction is well underway on the program’s 9.1 mile alignment extension through the cities of Glendora, San Dimas, La Verne, and Pomona, CA. To help maintain this success, the Construction Authority recently extended Hill International’s contract to provide program management services for the Extension.
Hill has been managing the program since 2009, providing expertise in design, construction, quality control, project controls, and third-party management. Hill professionals like Hiramoto function as an extension of the Authority’s staff, working in key roles to manage the planning, design, and construction of the Light Rail Program’s many elements.
Initially, Hill supported Phase 2A of the program, an 11.5 mile segment connecting Sierra Madre Villa Station in Pasadena to Azusa. That phase encompassed three design-build contracts involving bridges, stations, maintenance and operations facilities, trackwork, at-grade crossings, grade separations, parking facilities and other enhancements. With Hill’s support, Phase 2A was completed on time and within budget in 2015 and extended Gold Line service to the cities of Arcadia, Monrovia, Duarte, Irwindale, and Azusa.
Overall, Phase 2B will extend the Gold Line a further 12.3 miles, adding six stations from Glendora to Montclair. Due to increased construction cost realized during the competitive bidding process and available funds, the baseline design-build contract was executed in late 2018 covering Glendora to Pomona, and with a two-year contract option to extend into Claremont and Montclair.
The total program—approximately $3.5 billion and 24 miles—will conclude with the completion of the next sub-phase in 2028, connecting Los Angeles County to San Bernardino County and providing a sustainable and efficient transit link between Los Angeles and its northeastern suburbs. Despite the successes that Hill and the Construction Authority have already had with the Light Rail Program, as well as the more-optimistic COVID-19 outlook, the path forward will have its challenges.
