The Connecticut Department of Transportation (CTDOT) has announced plans to replace or overlay extruded aluminum highway sign panels along the entire length of Interstate 91. The project aims to enhance retroreflectivity and improve nighttime visibility for drivers. Signs included in the upgrade are large overhead and side-mounted guide signs, as well as on-ramp entrance signs that require replacement but are not part of other projects.
As part of this initiative, CTDOT will revise the exit numbering system on I-91 from sequential numbers to a mileage-based system, aligning with federal regulations. More information about the exit renumbering process is available at Exit Renumbering FAQ.
“Replacing these highway signs along I-91 will improve visibility and readability for motorists, particularly at night and during adverse weather conditions,” said Barry Schilling, CTDOT Project Manager. “In addition to improved retroreflectivity for motorist visibility, this project will also modernize I-91’s exit numbering system to a mileage-based format, to meet federal standards and provide consistency for drivers traveling throughout the region.”
The design phase is expected to be completed by February 2026, with construction set to begin in August 2026.
CTDOT stated its commitment to keeping the public informed and involved during such projects and encourages community members to share their concerns to help guide development. For further details about the project, individuals can contact Barry Schilling, Supervising Engineer, at Barry.Schilling@ct.gov referencing Project Number 0092-0702.
