Century Avenue will be closed under I-494 starting Tuesday, July 7 through August 30 due to bridge widening, Mn-DOT officials stated Thursday in an official update. Lake Road can be used as a detour.

Mn-DOT is undertaking a two-year road rehabilitation project on I-494 from Lake Road to I-94 that will connect existing auxiliary lanes between interchanges in order to provide three continuous lanes for traffic in each direction between the two points.

New concrete pavement will be installed over the existing pavement, and the southbound I-494 bridge over Century Avenue will be widened.

Freeway lighting north of Valley Creek Road will also be added, providing continuous lighting on I-494.

This summer's work will consist of rebuilding the right shoulders in order to handle traffic, then switching to the median area for drainage improvements and pavement widening.

The third lane in each direction will be open in 2010.
