PROJECT PURPOSE AND DESIGN

WHAT IS THE PURPOSE OF THE PROJECT?

Answer: The Veranda Street bridge nearing its 60th year of service and is exhibiting signs of advancing deterioration. The bridge is classified as structurally deficient. MaineDOT came up with a design solution to replace the bridge to ensure this vital transportation link continues to safely serve the public for generations to come.

An important project goal for the project is to replace the deteriorated Veranda Street Bridge with a shorter, low-maintenance structure and reconfigure Veranda Street to improve public safety while minimizing impacts to the public.

The proposed project is needed because 1) the existing bridge is nearing the end of its useful life based on condition and bridge geometrics, and 2) the roadway configuration beneath the bridge is confusing which contributes to a high incidence of crashes at the intersection of Veranda Street and the I-295 southbound on-ramp. This intersection is classified as a high crash location.

WHAT ARE OTHER CHANGES BEING MADE WITH THIS PROJECT?

Answer: The current bridge consists of three spans. The new bridge will be shorter and consist of only a single span. The remaining two spans of the existing bridge will be filled in to form embankments resulting in lower initial construction costs and lower long-term maintenance costs. The new bridge will also have a higher vertical clearance that meets current standards reducing the possibility of the bridge being struck by an over-height load.

The on- and off-ramps for Exit 9 leading to Veranda Street, and a portion of Veranda Street itself, will also be reconfigured as part of this project. The work includes the construction of modern signalized intersections at the end of each ramp to improve safety for all users.
Additionally, the grassed median of Veranda Street is being removed and the roadway is being shifted approximately 10 to 15 feet away from the homes on the street.

Once complete, the reconfigured Veranda Street will consist of two 11-foot-wide vehicle travel lanes, two five-foot-wide bicycle lanes, a five-foot-wide sidewalk on the north side of the roadway, and a multi-use path on the south side that extends to the Martin’s Point Bridge.
Finally, the revised roadway configuration will also allow for an open green space between the reconfigured Veranda Street and the nearby shoreline. This change accounts for nearly 1.5 acres of roadway/median to be converted into the green space area.

CONSTRUCTION METHOD

HOW IS THIS DIFFERENT FROM OTHER BRIDGE REPLACEMENTS, AND WHY DO I-295 AND VERANDA STREET NEED TO BE CLOSED?

Answer: The existing bridge carrying I-295 over Veranda Street is 60 years old and needs to be replaced. To reduce the long-term congestion of a multi-year replacement, and to increase the safety of the traveling public and workers during construction, the bridge replacement is being completed using Accelerated Bridge Construction (ABC). The method of ABC selected for this project involves building the upper portion of the new bridge to the side of the existing one on temporary supports. At the same time, the new bridge foundations will be built beneath the existing bridge. Then, while the roadways are closed, the new bridge will be lifted and “driven” into place using a Self-Propelled Modular Transporter (SPMT). An SPMT is essentially a large platform supported by many tires that can safely and efficiently move extremely heavy loads into place with great precision. I-295 needs to be closed to allow for the removal of the current bridge and to move the new bridge into place. Veranda Street needs to be closed to prepare for the work, to demolish the existing bridge, and to transport the new bridge into place.

WILL THERE BE ACCESS PROVIDED TO VIEW THE BRIDGE BEING MOVED?

Answer: Because of safety concerns at the active construction area, there will be no safe place for the public to view the work. Instead, two cameras have been installed and will be streaming live images and time-lapse views of the project. A time-lapse video of the movement of the bridge will be provided for viewing after the closure weekend.
