Structural Condition
Pioneer Gateway Pioneer Gateway is constructed of mortared stone masonry. The south pier is approximately 9’-8” wide by 6’-8” tall and 2’-8” thick. The north pier is approximately 9’-5” wide by 6’-8” tall and 2’-4” thick. The stones used to construct the piers are a mix of local red sandstone and granite. The stones are set in a hard mortar applied in different campaigns, one of which included large aggregate. It is unknown how deep below grade the piers extend. Generally Pioneer Gateway is in good structural condition. The piers appear to be plumb and no evidence of cracking of the masonry units or mortar. Some of the sandstone units are slightly eroded, however, none to the point of significant structural section loss. The most major threat to the structural stability of the Gateway is how close the vegetation is growing to the masonry (in some cases it is growing on the masonry structure). Not only can the vegetation harbor excess moisture against the structure and cause the sandstone units to weather quicker, but the root systems can also grow and extend into the structure and cause damage in the future.
