[29][30][31], The bridge closed for a month in 2000 to repair the bascules and perform other maintenance. A laser beam from a Laser Doppler Vibrometer is directed at the point of interest, and the vibration amplitude and frequency are extracted from the Doppler shift of the laser beam frequency due to the motion of the surface. Its construction came at the height of the extravagant Florida land boom of the 1920s, and the bridge is one of its greatest landmarks.
