Project Description

The Empire Avenue reconstruction and I-5 widening through Burbank includes the construction of 2 high occupancy vehicle (HOV) lanes, one lane in each direction. The freeway reconstruction involves substantial modifications to existing interchanges, adjacent railroad tracks and existing grade separations. Metrolink's Empire Avenue Grade Separation project also involves realignment and elevation of the existing Metrolink track and siding, and construction of new grade separations at Empire Avenue and Buena Vista Street. To accomplish this, a temporary prefabricated railroad bridge has been installed in order for the work to be completed and to facilitate continued railroad usage. Also, the existing underpass at San Fernando Road will be abandoned, infilled, graded, and landscaped.
