“To provide a safe, integrated, innovative and sustainable transportation system that supports Alberta’s economy & quality of life”

Alberta Transportation’s2015-18 Business Plan

Our Mission / Desired Outcomes

Desired Outcomes:- Well-integrated, multi-modal transportation

system- Sustainability & affordability of system - Safe & secure transportation system- Support environmental stewardship &

quality of life

Highways support Alberta’s Priority on Economy

4

• $20 billion of commodities are imported & exported using trucks

• Support the efficient movement of people and goods within the province

Challenges Overall

5

• Major capital investments are needed to provide key infrastructures for economic growth

• Bridge and Road rehabilitation are both underfunded

• Cross-asset investment optimization of limited funding is a challenge

Bridge Pavement

Design Life

Aging of System:

Note – older bridges designed for shorter service lives, smaller loads

Challenges for our Provincial Highway Network

7

• More provincial highways than any other province

Deteriorating condition

• Network continues to deteriorate

– Poor: 14.6% in 2011 to 16.5% predicted in 2017
