The project made the platforms level with the light rail vehicles, eliminating the need to step up onto the train cars.
The change allows for easier boarding for passengers who are mobility-impaired, as well as passengers with wheeled luggage, baby strollers or bicycles.
The Snell station will close for retrofit construction Monday, and is expected to be closed for six weeks, according to the VTA. The Santa Teresa station will also be under construction but a temporary station platform will be built so that riders can still use the station.
The retrofitting of station platforms began in February and is expected to be finished by the end of November, according to the VTA.
