Colorado State Highway Encroachment Permits (3-CO-c)
State Highway Encroachment Permits Process
3-CO-c.1 to 3-CO-c.2 — Will the Developer Construct, Relocate, Close, Modify, or Change the Use of a State Highway Access Point?
A developer must obtain a State Highway Access Permit and/or a State Utility-Special Use Permit to “construct, relocate, close, or modify access(es) to a state highway or when there are changes in use of such access point(s).” 2 CCR 601-1 §2.3(3)(a), State Highway Access Code.
If the project will not encroach on any state highway rights-of-way, the developer will not need a state highway encroachment permit. However, localities may also have their own encroachment permits for encroachments on local rights-of-way. A developer should consult with local authorities for encroachments on local right-of-ways.
3-CO-c.3 to 3-CO-c.5 — Will the Developer Perform Utility Accommodation Work within a State Highway Right-of-Way?
Utility owners must obtain a Utility-Special Use Permit from the Colorado Department of Transportation prior to performing any utility accommodation work, including the initial installation, relocation, maintenance activities not covered under an existing permit, or for facilities removal. 2 CCR 601-18 §220.127.116.11, State Utility Code. If a developer needs a Utility-Special Use Permit, see:

3-CO-e If the developer is not performing utility accommodation work, then a developer only needs a State Highway Access Permit. For more information regarding a State Highway Access Permit, see:
Note, a developer may need both a State Highway Access Permit and a State Utility-Special Use Permit.
