A deflection indicating adjustable highway straight-edge. The highway straight-edge is designed to effectively level wet concrete by allowing the user to determine when the device is not straight and provides the user with a means of controlled adjustment for straightening. In the preferred embodiment, a laser light beam and electronic sensing device is used to detect deflection of the straight-edge. Undesirable deflection can be eliminated through the external adjustment of steel tension cables inside the straight-edge tube. In an alternative embodiment of the invention, deflection is detected by means of an electrically conducting wire having contact points to indicate that the straight-edge requires adjustment. In another embodiment, a steel wire or string line stretched tightly inside the straight-edge tube indicates deflection requiring adjustment.
