The third and final ramp to the Pomona Freeway (SR-60) from Lemon Avenue is due to open sometime in July, bringing to a close a key multimillion-dollar freeway interchange project many years in the making.
Planning and design of the three-legged Lemon Avenue Interchange project began more than 15 years ago and construction started in September 2016, however the project’s history extends back more than 50 years. In March 1968, plans for the construction of an interchange at Lemon Avenue were included in a Freeway Agreement between County of Los Angeles and the State but never materialized because of a lack of funding.
Efforts by the Cities of Diamond Bar and Industry, in cooperation with Caltrans and the Federal Highway Administration, moved the project forward, and last month the westbound on-ramp and eastbound off-ramp from Lemon Avenue to SR-60 opened. It is anticipated that the eastbound on-ramp and an auxiliary lane to SB SR-57 will open sometime this month. Also as part of this project, the existing freeway ramps near Brea Canyon Road and Golden Springs Drive will be permanently closed.
The opening of the new interchange at Lemon Avenue and elimination of the eastbound on- and off-ramps at Brea Canyon Road and Golden Springs Drive will help address congestion and safety issues both on the freeway and on nearby surface streets. It will provide more direct freeway access to delivery trucks heading into and leaving local industrial areas, and make it easier and safer for drivers traveling east on the SR-60 to merge onto the southbound SR-57.
