Foothill Gold Line design completed

Foothill Gold LineFoothill Gold Line project reached a major milestone as the design of the Glendora – Pomona section has been completed. The section will have a length of 14.6 km and will be served by four stations.

The design-build project was awarded to Kiewit-Parsons joint venture (KPJV) in October 2019, and the first year of the contract was spent focused on completing the design to start major construction.

The construction begun in July 2020 and in August 2021 reached a 36% completion.

The project design is a significant element of the design-build project which is completed in packages. Disciplines such as the track, stations and systems are completed in packages along the entire LRT line, while civil design elements like roads, lighting, drainage and walls are completed in segments. The 19 bridge structures being built on the project are each designed individually. All the design of the
elements go through multiple levels of approval – 30%, 60%, 85%, 100% and then are approved for construction (AFC) and are often reviewed by multiple agencies at each stage. With this latest announcement, all elements of the project have reached the final level of approval (Approved for Construction).

The work on the Foothill Gold Line from Glendora to Pomona has been able to continue on schedule through 2020 amid the Covid-19 pandemic. The base project along this section is currently six months ahead of the contractual substantial completion deadline of January 2025.

The design-build contract does include an option to have the KPJV team complete the entire project from Glendora to Montclair if additional funding is secured by early October 2021. If
that is achieved, the entire 12.3-mile (19.8 km), six-station project will be completed altogether in early 2026.

The section of the project in Los Angeles County is funded mostly by Measure M, along with residual funds from Measure R not used to complete the Pasadena to Azusa segment. San Bernardino County is responsible to fund their section of the project to Montclair (in San Bernardino County). The State of California has provided USD 300 million in funding through a TIRCP grant awarded in 2018 to both counties.
