If you drive through the Euclid Avenue interchange in Ontario and Upland, you’ll see a lot of activity and a lot of bare dirt where grass and trees once grew. (And where brick planters rose in the portion over the freeway.) I visit and take photos of the work, which will result, eventually, in a wider freeway and an improved interchange. Also, a favorite haunt of mine, Nancy May’s ’50s Cafe in Rancho Cucamonga, opened Monday for the first time since mid-March. I write about both in Wednesday’s column.
