Frequently Asked Questions, From DOT Website:
Q: Why are the exits being renumbered?
A: The exits are being renumbered to conform to Federal standards. Reference location (mileage) based exit numbering is a requirement of the MUTCD (Manual on Uniform Traffic Control Devices), Section 2E.31, published by the Federal Highway Administration. The MUTCD is the national standard and is adopted by reference in the Federal Code of Regulations Title 23: Highways Part 655.603.
Q: What are the benefits to a mileage-based exit numbering system?
A: – National Uniformity
Same exit numbering system as almost every other state.
Driver friendly navigation
Allows drivers to quickly determine distances to destinations
Easier to calculate miles traveled
More accurate emergency response
Improves reporting of highway incidents, resulting in better navigation of emergency services
Easier to add future exits without renumbering entire corridor
Q: Which highways will get new exit numbers?
A: All limited access roadways within the State will be renumbered to mileage-based numbering as required by the Federal Highway Administration (FHWA).
Q: How are the new exit numbers determined?
A: Exit numbers will be determined based on the mileage contained in the CTDOT Linear Referencing System. Mileage typically runs from south to north and west to east. –
No Exit 0
Mileage 0.00 – 1.49 = Exit 1
Mileage 1.50 – 2.99 = Exit 2
Mileage 3.00 – 3.99 and beyond.
+ Round down to the nearest whole mile
CTDOT may round up or down to the next nearest whole mile to reduce suffix letters or utilize the existing exit number.
Splits on off-ramps will not be designated as separate numbers/suffix letters.
