School Boulevard Roundabouts

The School Boulevard Improvement Project replaces two all-way stop-controlled intersections at School Boulevard and Cedar Street, and School Boulevard and Edmonson Avenue, with single-lane roundabouts. Work will take place on School Boulevard from Highway 25 to Country Lane.

Timeline

• As of September 13, both intersections are now open. Final restoration work will be completed in the following weeks.
• Construction began the week of May 5. Full completion of the project is expected in September 2025. Due to weather-related delays, project completion was delayed by an estimated three weeks.
• Working hours for the project are 7 a.m. to 7 p.m. Monday through Saturday.
• Construction will be done in phases. Detours and road closures will change throughout the project.
• See "Project History"  below for information on completed phases.

Traffic and Access Information

• One lane of traffic will generally remain open in each direction along School Boulevard and Cedar Street.
• Edmonson Avenue north and south of School Boulevard will be closed for the duration of the project.
• The intersection of School Boulevard and Edmonson Avenue will be completely closed for a short period near the end of the project to complete the roundabout construction.
• Access to driveways will be maintained, although some driveway entrances within the street right-of-way may be partially removed and replaced as new street surfaces are constructed.
• Temporary access restrictions may occur as the project progresses past driveways and intersections.

Project Scope

• Full depth reclamation of School Boulevard between Highway 25 and Country Lane.
• Full depth reclamation as required for Cedar Street and Edmonson Avenue for roundabout construction.
• Spot curb and gutter replacement and repair of existing drainage issues.
• Replace all non-compliant ADA ramps throughout the project area with new ADA ramps and sidewalk as required for the roundabout construction.
• Construct a pathway on the south side of School Boulevard between Country Avenue and Edmonson Avenue.
• Install lights on the new pathway and connect to the existing lighting system.
• Removal of the center medians between Highway 25 and Edmonson Avenue and install a two-way left turn lane.

• Install roundabout landscaping consistent with The Pointes at Cedar zoning district.

Project Background

The City of Monticello successfully secured grant funds for the construction of two single-lane roundabouts on School Boulevard at the intersections with Cedar Street and Edmonson Avenue. Both intersections are currently controlled with 4-way stop signs. A traffic analysis (PDF), completed during The Pointes at Cedar master planning process, recommended constructing roundabouts for greater safety and efficiency.

The City will receive $485,000 through the Carbon Reduction Program (CRP) for the Edmonson intersection improvements. In addition, the City was awarded $1,000,000 through the Surface Transportation Block Grant Program (STBGP) for improvements at the intersection of School Boulevard and Cedar Street.
