The Sentry Bridge Replacement at Watkins Glen State Park

At Watkins Glen State Park, one of the region’s most visited natural landmarks, a critical infrastructure upgrade is underway. Twin Tier Constructors Inc., a division of Power & Construction Group, has been leading the removal and replacement of the historic Sentry Bridge, ensuring safe access while preserving the park’s character.
The project combines precision engineering, environmental care, and logistical coordination in a setting that presents both natural beauty and construction challenges.

The Challenge

The original Sentry Bridge had reached the end of its service life, requiring full replacement to meet modern safety standards. Located within a heavily trafficked state park, the project demanded:

• Careful demolition without disrupting the surrounding landscape
• Limited access for heavy equipment
• Protection of nearby trails, water features, and natural rock formations
• Tight timelines aligned with seasonal park usage

Working in a confined and environmentally sensitive area required detailed planning at every stage.

Project Approach

Twin Tier Constructors Inc. approached the project in phases, beginning with the controlled removal of the existing structure. Crews utilized specialized equipment and staging techniques to safely dismantle the bridge while minimizing impact on the park environment.

Key elements of the approach included:

• Coordinated material removal and site stabilization
• Strategic equipment placement to reduce ground disturbance
• Continuous safety oversight for both workers and the public

Each phase was executed with a focus on efficiency, safety, and environmental responsibility.

Installation of the New Bridge

In April 2026, the project reached a major milestone with the installation of the new Sentry Bridge. This phase required precise coordination, including crane operations and carefully timed placement of structural components.

The installation process drew significant attention due to its scale and complexity, marking a visible transformation of the site.

The new structure is designed to:

• Improve long-term durability
• Enhance visitor safety
• Maintain the visual integrity of the park

Commitment to Quality & Community

As part of Power & Construction Group, Twin Tier Constructors Inc. brings deep experience in infrastructure and bridge construction across the region. This project reflects that expertise, along with a commitment to:

• Delivering high-quality, lasting infrastructure
• Protecting natural environments
• Supporting public spaces that serve local communities

The Sentry Bridge replacement stands as a testament to careful planning, skilled execution, and strong collaboration. It is scheduled to reopen on July 4, 2026.
