Metrolink commute -- City of Industry Station question (Riverside, Diamond Bar: construction, move to)

[frank.usc]

Hi,

I used to commute from Riverside to Union Station by Metrolink. I'll move to Diamond Bar soon so I'll use the City of Industry station. I know there's construction on Brea Canyon Road and I can't access the parking lot from south unless through the lemon street detour. My question is: is there any other way other than lemon street to the parking lot from south side of Brea Canyon road? Lemon street detour looks like a big loop to me (at least on the map). Or is there any street parking on the south side around so I can walk to the platform through a pedestrain crossing or something like that?

Thanks!

Frank
