Lunda Construction Awarded Roberts Street Railroad Bridge Replacement Project in Minnesota

Key Terms

vertical lift technical

The ability of an aircraft or vehicle to rise and descend straight up and down without a runway, including helicopters, tiltrotors, and electric vertical takeoff and landing (eVTOL) vehicles. Think of it like a car that can also act like an elevator, letting it operate in tight urban spaces or remote sites where runways don’t exist. For investors, vertical lift describes a category of aerospace technology whose development, regulation, and operating costs can affect market demand and company valuations.

rolling bascule truss span bridge technical

A rolling bascule truss span bridge is a movable bridge whose roadway is built as a truss and lifts by rolling backward on a curved track with counterweights, like a giant hinged beam that also rolls to open for traffic below. For investors, the design matters because the mechanical lifting system and truss structure drive construction and maintenance costs, operational reliability, and potential traffic or shipping delays that can affect nearby businesses and public budgets.
