Chelsea Viaduct Rehabilitation ProjectProject Overview & Need

The Chelsea Viaduct is structurally deficient and in need of repair and rehabilitation. The viaduct, first constructed in 1956—’57, carries 63,000 vehicles daily on Route 1 (including MBTA Route 111) through the “Chelsea Curves” to the Tobin Bridge, providing a crucial transportation link between Chelsea, the northern suburbs, and Boston.

To ensure the safety of this critical connection, MassDOT has assembled a team to rehabilitate and restore the superstructure and roadway to a state of good repair.

Working with the City of Chelsea, abutting residents, roadway users, and other stakeholders, the team will design a plan for construction that minimizes and mitigates temporary construction impacts, and coordinates with the Tobin Bridge Rehabilitation Project (#605957). This will shorten the overall period during which Chelsea experiences construction impacts.

Context and Known Concerns

The Chelsea Viaduct runs through a dense neighborhood, with homes and businesses abutting the structure, and parking lots directly underneath. The state of the viaduct, combined with the need to coordinate with the Tobin project’s 2017-2020 construction period, is leading MassDOT to consider Accelerated Bridge Construction (ABC) techniques, like those used during the I-93 Fast 14 Project. This will allow construction to be completed more quickly, and the duration of impacts lessened, compared to traditional methods.

To gather input and plan to mitigate impacts associated with the project, the team will be performing a full range of public outreach and community engagement, environmental justice analysis, structural and survey analysis, and both internal and interagency coordination. All of these may illuminate concerns, ideas, and other variables that we cannot yet anticipate. Regardless, we expect construction to include:

• Mitigation and control of temporary construction impacts to residents and abutters, such as dust and noise

• Temporary relocations of Arlington St @ Fifth St MBTA bus stop (serving Routes 111, 112, 114), and of parking impacted by work-zones

• Traffic diversions and detours, including ramp closures, during replacement of the superstructure

• Night & possible weekend work, as a way to shorten construction

In addition to those outlined above, one purpose of the public outreach process is to uncover other impacts that may be expected. We want to hear from you.

Schedule & Process

The team has been working on preliminary design plans and will be submitting 25% Progress Plans in preparation for the Design Public Hearing (25% DPH). The 25% DPH is anticipated for Fall 2017. Following the DPH and internal review, the team will refine the plans to Final Design, and work to integrate public and internal comments to the extent feasible. MassDOT’s goal is to advertise the project for construction bidding in March 2018, and begin construction that year, to meet the timeframe for the Tobin Bridge project.

As currently envisioned, the first stage of the project will be 1.5 – 2 years of substructure work, to retrofit and repair the supports for the new superstructure. Traffic and night-work impacts will be low during this stage. Next, the superstructure and deck will be repaired and replaced; this stage will include heavier traffic and construction-related impacts, including night and possible weekend work, ramp closures, and traffic detours. This final stage will culminate in a restored, rehabilitated, and reinforced Chelsea Viaduct.
