HWY 1A IMPROVEMENTS PROJECT: 5^th AVENUE ACCESS 

Crews are in the final stretch for 2022 construction work. Over the next few weeks, residents should anticipate some additional traffic safety measures in place, including:

• Speed limits will be reduced to 30km/h throughout the construction areas. 
• Additional cement barriers will be placed, which will limit traffic flow to single eastbound and westbound lanes in most of the construction area. 
• Starting as early as this weekend, access to Fifth Avenue from HWY 1A will be closed as crews work to build the new Fifth Avenue intersection. Follow the detour signage. 

Do your part to keep construction zones safe for everyone – slow down and be patient. We all deserve a safe workplace.
