M3 Inner City Bypass
(ICB) is a major motorway standard
road in Brisbane
. The 4.5km bypass is north of the city. Bypassing the Brisbane central business district
, it connects Brisbane’s Pacific Motorway
and Go Between Bridge
at Hale Street
to Kingsford Smith Drive
, the Clem Jones Tunnel
and Lutwyche Road
following the Exhibition railway line
for the majority of its length.
The route is marked as the M3
from the western part of the route, up until the Horace Street interchange.
The motorway cost $220m to complete and incorporates a total of six lanes, four tunnels, 18 bridges and was the largest infrastructure engineering project undertaken in Queensland for decades. The route also includes a 350m long tunnel under the RNA Showgrounds
. There is no toll for use of this roadway.
The ICB, built by the Brisbane City Council, is considered one of the most successful road projects in Brisbane, completed well before schedule, on budget, and to date is one of the most used road corridors in the city. Significant congestion occurs in lanes heading towards Hale Street at peak times, this has resulted in a nickname of the "Inner City Car Park".
The Inner City Bypass was built in 3 stages:
- Stage 1 – Hale Street to Campbell Street which opened during November 2001
- Stage 2 – Campbell Street to Abbotsford Road which opened during February 2002
- Stage 3 – Abbotsford Road to Kingsford Smith Drive which opened during July 2002
