FHWA Every Day Counts Initiative Designed to identify and deploy innovation aimed at shortening project

delivery, enhancing the safety of our roadways and protecting the

environment.

SHRP 2 Solutions

RIDOT Goals • Safety

• Innovative

• Using Accelerated Bridge Construction Methods • Precast substructure, PBE’s

• Minimize Time • Road closure eliminated phasing

• Cost Effective • Balanced accelerating construction with user costs

• Efficient Intermodal Transportation Network

• Restored link from East Bay to Providence Crossing

SHRP 2 Solutions

RIDOT Goals (Continued) • Public Attentiveness

• Minimize Public Impact • Replace in 20 days with ABC, 2+ years conventional

• Increase Public Awareness • City Officials • Attended Council Meeting • Outreach through multiple media venues: radio,

social, paper, internet, link to web cam on DOT website, door to door with handouts

Why ABC for New Bridge? • No phase construction option due to narrow 23’ – 0” roadway width

• Significant reduction of bridge closure time

• Detour options available

• Reduce impact to traffic and the public
