Newer group high masts meets Old highmasts

This is where the older part of I-95 built in 1970 ended until 1974 additions were added. The highmasts you see behind the overpass (with 4 fixtures) are currently MH, which was believed to be MV! The one in front is HPS and the rows continues HPS until north of Baltimore passing the intersection of North side of the beltway the 695

I am not sure the make and brand of those 2 styles of those highmasts although those HPS ones look very similar to the WideLite highmast as gailgrove mentioned, but with slight differences, including use of refractors.
