The Project anticipates FHWA approval later in 2025 prior to beginning Final Design or creation of construction plans. The first project envisioned is I-393 bridge over I-93 to remove the bridge from the NHDOT’s red-list and starting in 2028.
The Bow-Concord project will require multiple construction projects and will be constrained by available funds. The NH 2025-2034 Ten-Year-Plan currently programs construction funds through 2034 with additional funding planned beyond to complete the project.
The estimated 2024 cost is roughly $370 million.
For a project of this size and scale, partial and full property acquisitions are common.
The proposed alternative would require 32 partial property acquisitions (14 in Bow, and 18 in Concord) and 11 full property acquisitions (6 in Bow, and 5 in Concord).
The DOT Bureau of Right-of-Way is responsible for contacting property owners and handling the acquisition of property rights required for transportation projects.
For more information regarding property acquisitions, please read Your Land and New Hampshire's Highways.
There are 33 bridges within the project limits that are proposed to be rehabilitated, replaced or added.
Bicycle and pedestrian accommodations will be incorporated into the final design of the project including extension of the Merrimack River Greenway Trail (MRGT) from the Loudon Road Bridge over Merrimack River through the Project to Storrs Street.

Proposed improvements for multi-modal infrastructure:
Currently, NHDOT has programmed Federal Highway and Turnpike Toll funds to pay for the project. There are no local funds for the project.
The posted speed for I-93, I-89, and I-393 within the City of Concord Urban Compact is 55 mph and is not proposed to change in the project change.
I-93 was originally designed to meet 60 mph when the project was constructed in 1950s. The Project is using the existing or as-built alignment and does not increase the design speed.
