14.1 Virginia's Six State-Owned Bridge-Tunnel Facilities and the Rural Tunnels

14.1 Virginia's Six State-Owned Bridge-Tunnel Facilities and the Rural Tunnels

[!IMPORTANT] The governing regulation is 24VAC30-61, Rules and Regulations Governing the Transportation of Hazardous Materials Through Bridge-Tunnel Facilities, adopted by the Virginia Department of Transportation under Va. Code §§ 33.2-210 and 33.2-300. It applies to all transporters of hazardous materials — interstate and intrastate, public and private — traveling through the state-owned bridge-tunnel facilities it lists. Know the chapter by its four sections, because they are numbered in a way that trips people up.

The Four Sections of 24VAC30-61

Section -20 is only the list. The rural rule lives in -30 and the urban rule lives in -40. Prep material that cites "-20" for the rural tunnels or "-30" for the urban tunnels is citing the wrong sections.

The Six State-Owned Facilities (24VAC30-61-20)

There are six state-owned bridge-tunnel facilities in the Commonwealth: two rural and four urban.

VDOT publishes a telephone number for each facility on its hazardous materials page. Program the numbers for the facilities on your lane into your phone before you need them.

[!NOTE] The Chesapeake Bay Bridge-Tunnel is not on this list. It is not a state-owned facility governed by 24VAC30-61; it operates under its own commission and its own rules, covered in Section 14.3. Neither is the Roanoke Airport Tunnel, also covered there.

Rural Facilities: No Facility-Specific Restrictions (24VAC30-61-30)

Many drivers assume every tunnel in Virginia bans hazardous materials. That is wrong, and the regulation says so directly:

For the two rural tunnels, no restrictions apply on the transport of hazardous materials, so long as transporters and shippers are in compliance with 49 CFR 100 through 180 and any applicable state regulations.

1. Big Walker Mountain Tunnel (Interstate 77)

Located on Interstate 77 between Bland and Wytheville in southwestern Virginia. A placarded load — gasoline, propane, corrosive acids, oxidizers, standard industrial chemicals — may transit the tunnel provided the shipment complies with the federal Hazardous Materials Regulations.

2. East River Mountain Tunnel (Interstate 77)

Located on Interstate 77 at the Virginia–West Virginia line near Bluefield. Same rule: no facility-specific hazmat prohibition, no special permit, no VDOT escort — just federal compliance.

The Commissioner's Emergency Authority

There is one qualifier, and it is worth knowing because it can change on the day you are driving:

The Commissioner of Highways may, at any time, impose emergency or temporary restrictions on the transport of hazardous materials through these facilities, so long as sufficient advance signage is positioned to allow for a reasonable detour.

Practical meaning: "no restrictions" is the standing rule, not a guarantee for a specific trip. If you see hazmat restriction signage on the I-77 approach, a temporary restriction is in force and you take the detour.

Common Exam Traps & Pitfalls

• Trap: "All Virginia tunnels ban hazmat."
  • The Legal Reality: The two rural I-77 mountain tunnels carry no facility-specific hazardous materials restrictions. Only the four urban facilities restrict by hazard class.
• Trap: Miscounting the facilities.
  • The Legal Reality: Six state-owned bridge-tunnel facilities — two rural, four urban. The Chesapeake Bay Bridge-Tunnel is a seventh crossing but is not one of the six and is not governed by 24VAC30-61.
• Trap: "The rural exemption is permanent."
  • The Legal Reality: The Commissioner of Highways may impose emergency or temporary restrictions at any time, with advance signage allowing a reasonable detour.

Reading the Regulation Itself

24VAC30-61-10 states the scope in a single sentence: "This chapter establishes the rules by which all transporters of hazardous materials are governed while traveling through certain bridge-tunnel facilities." "All transporters" is literal — interstate and intrastate, for-hire and private, common carrier and company fleet alike.

24VAC30-61-20 is equally spare: "The following table lists the six state-owned bridge-tunnel facilities in the Commonwealth to which this chapter applies," followed by "For purposes of this chapter, the facilities listed in the table in this section are classified into two groups: rural and urban." The rural/urban split is not trainer shorthand — it is the operative classification in the regulation, and it alone decides whether -30 or -40 governs your load.

Note that the authority lines differ by section: -10 and -20 rest on Va. Code §§ 33.2-210 and 33.2-300, while the rural rule at -30 rests on § 33.2-210 alone.

Study From the Current Text

24VAC30-61-30 derives from VR385-01-05:1 § 3, effective November 15, 1995, and has been amended four times since: twice in 2011, again effective May 6, 2024, and most recently effective February 25, 2026 (Virginia Register Volume 42, Issue 12). Third-party CDL prep material that predates the 2024 and 2026 amendments is a genuine hazard on this topic — some commercial mirrors of the chapter still show a stale table. Verify any tunnel list against the Virginia Administrative Code text before you rely on it.

Facility Contact Numbers

The regulation itself directs transporters to VDOT's hazardous materials page for facility contact information. Program the numbers for the facilities on your lane before you need them:

The Chesapeake Bay Bridge-Tunnel line is listed here only because VDOT publishes it on the same page — which is precisely how drivers come to believe it is a seventh state-owned facility. It is not, and its rules are different; see Section 14.3.

Geography Worth Knowing on the I-77 Run

The East River Mountain Tunnel is 5,654 feet long and sits 54% in Virginia and 46% in West Virginia, according to VDOT. You cross a state line inside the tube, so two states' enforcement interests attach to the same load on the same trip, and a temporary restriction posted on one approach governs the direction you are actually travelling. The Big Walker Mountain Tunnel lies to the south in Bland County, roughly twenty miles from East River; heading north from Wytheville you meet Big Walker first and East River second.

Because both tunnels carry the Interstate through a ridge, any hazmat detour around either one is long and slow. That is exactly why -30 conditions the Commissioner's emergency authority on "sufficient advanced signage ... to allow for a reasonable detour" rather than permitting an unannounced closure at the portal. On any I-77 hazmat run, check VDOT's 511 travel information before departure and treat posted restriction signage as controlling.
