LEGISLATION: CONGESTION RELIEF

HRTAC (HB 1253, 2014) • “…shall give priority to those projects that are expected

to provide the greatest impact on reducing congestion for the greatest number of citizens residing within Planning District 23…”

Statewide Prioritization Process (HB 2, 2014) • “…Hampton Roads highway construction districts…shall

ensure that congestion mitigation…is weighted highest among the factors in the prioritization process…” • 45% weighted factor in Hampton Roads

HRCS SEIS PURPOSE AND NEED

“The purpose of the HRCS is to relieve congestion at the I-64 HRBT in a manner that improves accessibility, transit, emergency evacuation, and military and goods movement along the primary transportation corridors in the Hampton Roads region, including the I-64, I-664, I-564, and VA 164 corridors.”

9

ALTERNATIVE A • Improvements to I-64

between I-664 (Hampton) and I-564 (Norfolk)

• Widens existing facility to six-lanes

• Improvements would be largely confined to existing right-of-way

• Cost: $3.3 Billion (2016$) – includes a 40% Contingency

10

ALTERNATIVE B Includes: • All Alternative A

improvements • New bridge/tunnel across

Elizabeth River • New highway along east

side of Craney Island to Route 164 (Portsmouth)

• Widen Route 164 to I-664


11

ALTERNATIVE C Includes: • Widen I-664 from I-64

(Hampton) to I-264 (Chesapeake)

• New connector between I-664 and I-564

• New highway along east side of Craney Island to Route 164 (Portsmouth)

• Transit only lanes


12

ALTERNATIVE D • Includes all components of

Alternatives B and C without transit only lanes

• A v/c > 1.0 indicates that the roadway experiences congestion.

• Volume/Capacity (v/c) is a measure that reflects mobility on a roadway.

• Compares roadway demand (vehicle volumes) with roadway supply (carrying capacity).

DISCUSSION

ADDITIONAL RESOURCES

HRCS SEIS PURPOSE AND NEED Accommodate Travel Demand • capacity is inadequate on the Study Area Corridors, contributing to congestion at the HRBT

Improve Transit Access • the lack of transit access across the Hampton Roads waterway

Increase Regional Accessibility • limited number of water crossings and inadequate highway capacity and severe congestion decrease

accessibility

Address Geometric Deficiencies • insufficient vertical and horizontal clearance at the HRBT contribute to congestion

Enhance Emergency Evacuation Capability • increase capacity for emergency evacuation, particularly at the HRBT

Improve Strategic Military Connectivity • congestion impedes military movement missions

Increase Access to Port Facilities • inadequate access to interstate highway travel in the Study Area Corridors impacts regional commerce

33

Sections that comprise the alternatives retained for analysis

3-4-3 Concept

3 lanes on land within existing R.O.W.

trestle 4 tunnel lanes trestle

Legend: Existing Proposed

1 Capacity of Existing HRBT, A Method of Estimating the Impact of Crossing Closures, HRTPO, Oct. 2013 2 Capacity of Existing Midtown Tunnel, A Method of Estimating the Impact of Crossing Closures, HRTPO, Oct. 2013

Approach Lanes

3 ln × 2100 vphpl = 6,300 vph

Capacity

Exit Lanes

3 ln × 2100 vphpl = 6,300 vph

Capacity

System Capacity: 6,300 vehicles per hour (vph)

Tunnel Lanes

4 ln × 1600(1) vphpl = 6,400 vph

Capacity

3 lanes on land within existing R.O.W.

37

By re-purposing the four (4) existing lanes in the EB and WB tubes as three (3) WB lanes, the 3-3-3 does not use one of the existing lanes:

As a result of not using an existing lane, the 3-3-3 would operate at LOS F. Given that the 3-4-3 concept—applicable to Alts A, B, and D—would potentially

be relatively uncongested, and would thereby move 30% more vehicles and move them at higher speeds as compared to the 3-3-3, the 3-4-3 has great potential.

Given that “if the 3-4-3 concept is identified as part of the Preferred Alternative [PA], it would be analyzed in great detail in the Final SEIS….”, HRTPO staff recommends that the Board consider identifying the 3-4-3 concept as part of its PA (if A, B, or D).
