Description:  This project will replace the existing outdated traffic signal equipment with a new signal that meets current design standards. New mast arms, signal heads, pedestrian signals, accessible curb ramps, signal detection and signal controller will be included.

Status:  The project is currently seeking proposals from engineering consulting firms for the design of the project.

Estimated time of Completion:  Design would be completed in 2021, with construction in 2022, depending on funding.

Estimated Cost: Design:$25,000. Construction:  $250,000

Funding Source: 04-795-393-00-100-452-079023

Designer/Contractor: TBD
 

Maplewood Avenue Bridge Project

This project is the replacement of the Maplewood Avenue Bridge at the North Mill Pond. Previous planning for this project as an out-year has been expedited due to the critical need for replacement identified in the Bridge Master Plan. The City is working to obtain the 80% NHDOT State Bridge Aid Program funds. If the funds are not available, general obligation bonding will be needed to complete this project. Improvements will include new sea walls, replacement of the existing water main and gravity sewer.

This project is currently in design and is identified in the FY 22 Capital Improvements Plan for funding in FY22.  The current anticipated schedule would be complete design in the fall of 2021 with construction to start the spring of 2022 to replace and repair the existing structure including new sidewalks. This is not a "Complete Streets" plan.

CIP TSM-19-PW-70: SAGAMORE AVENUE SIDEWALK

Description: This project will entail construction of a new sidewalk along Sagamore Avenue from Odiorne Point Road to the old Moose Club access road.

CIP TSM-95-PW-72: CITYWIDE SIDEWALK RECONSTRUCTION PROGRAM

Description: The Public Works Department created and conducted a conditional sidewalk assessment of City maintained sidewalks. The assessment contains detailed information on 77 miles of sidewalk, not including those within parks, fields and other City maintained facilities. The results give staff a clear depiction of the overall conditions. This project consists of sidewalks identified as being in poor to fair condition. Reconstruction work is based on need and coordinated with other street and utility improvements.

CIP TSM-10-PW-73: CITYWIDE TRAFFIC SIGNAL UPGRADE PROGRAM

Description: The City continues to replace antiquated signal systems throughout the City. These replacements improve traffic flow, emergency response, efficiency and safety at these intersections. The upgrades include new traffic signals, controllers, pedestrian indicators and minor roadwork at each intersection. The signal system at Middle Street and Miller Avenue / Summer Street has been identified as needing improvements.

CIP TSM-18-PW-77: CITYWIDE BRIDGE IMPROVEMENTS

Description: This project provides for the maintenance of City bridges. Typical bridge maintenance activities include sealing the concrete surfaces, replacing the pavement surfaces, replacing the bridge membranes and replacing, maintaining or upgrading railing systems and fences. Funds are based on the Bridge Master Plan recommendations for the highest priority repairs including Kearsarge Way Bridge and Market Street Bridges over North Mill Pond.

CIP Preliminary to FY24 TSM-08-PW/NH-78: CATE STREET BRIDGE REPLACEMENT

Description: This bridge is past its intended 50-year design life and it cannot handle heavy truck volumes and loads. The bridge needs to be replaced. Since the Portsmouth Senior Activity Center on Cottage Street is being redeveloped, residents have asked for the bridge to remain open if the median on the Route 1 Bypass is extended past Cottage Street to ensure emergency vehicle access to the Portsmouth Hospital.

CIP FY22 -- TSM-94-PW-82: STREET PAVING, MANAGEMENT AND REHABILITATION

Description: The City began a Pavement Condition Management Program in 1993. An annual report updating the City’s pavement management system is completed as part of this program. City road conditions are evaluated, the road network conditions and budget requirements are analyzed, and road-paving programs are developed. The report provides recommended funding to maintain street conditions at the current level. These are capital costs. They are implemented over a two-year period with an expected life of 20 years. The Public Works operational budget includes maintenance work costs with an expected life of 10 years.

 

FY22 $50k CIP BI-15-PW-36: CITYWIDE RETAINING WALLS REPAIRS AND IMPROVEMENTS

Description: The City owns over 30 retaining walls. This project will involve repairing failing retaining walls that are at risk of damaging private properties adjacent to them. The walls around the Municipal Complex are included in this project.
