<p>Tests on the movable grid deck, shown in the photograph, indicated the need for replacement that could not wait until the construction of the new bridge. In April and May 2001, these decks were replaced in four weekend night lane closures. Exceeding the contract specifications and the schedule developed by the contractor, there was minimal disruption to traffic. Media outreach assisted in warning of the possible travel disruptions. The replacement of the grid deck was completed on May 6, 2001.</p> <hr /> <p><em>Photo Credit: Stephanie Spears, PCC</em></p>
<p>The moveable span is comprised of a steel grid deck. This deck is raised by the operator in the tower to the right. Notice the traffic barrier in the foreground. Each three-lane section has two leaves that join. Joints must meet prior to opening to traffic. Recent studies indicate that the 50 foot naivigational clearance requires approximately 260 openings per year with the US Coast Guard requirements that prohibit openings during certain time periods (i.e., weekday peak periods).</p> <hr /> <p><em>Photo Credit: Stephanie Spears, PCC</em></p>
