Oak Hill Parkway: Project Update
The Oak Hill Parkway team is making great strides so far in 2023. Due to the need for additional bridge and roadway construction, there will be changes coming to the William Cannon Drive intersection starting this month. 
  • Crews will begin to remove the current curb-separated left-turn lanes on eastbound and westbound US 290 that drivers use to turn onto northbound and southbound William Cannon Drive. Barrels will be in place to delineate traffic lanes.
  • In March the US 290 and William Cannon Drive intersection will change from a “continuous flow” intersection to a “typical” intersection. This means the location of the left-turn lanes will be shifted next to the thru-lanes.
  • The US 290 and William Cannon Drive intersection will remain a “typical” intersection when Oak Hill Parkway is complete.
These traffic shifts will give crews the space to finish the new William Cannon Drive lanes north of US 290 and continue construction of the new US 290 frontage roads and new US 290 mainlane bridges in the area.
Essential Detours
A major traffic shift scheduled to begin in March will take place along US 290 near Joe Tanner Lane.
  • Both the existing eastbound US 290 mainlanes and eastbound US 290 frontage road will close west of Joe Tanner Lane.
  • Eastbound US 290 traffic will be shifted onto temporary pavement next to the existing westbound US 290 lanes, with barriers to separate each direction of traffic.
  • During this time, two lanes will be open in each direction of US 290 between Joe Tanner Lane and Monterey Oaks Boulevard. This traffic pattern will remain in place for at least 6 months.
  • The new McCarty Lane will reopen after being closed since April 2022. Connectivity between McCarty Lane and US 290 will be maintained from a temporary access point near the Hampton Inn that ties tying into the newly built eastbound US 290 frontage road.
  • Joe Tanner Lane at US 290 will close as well during this work. Access to Joe Tanner Lane will be maintained from McCarty Lane.
These closures and detours will provide Oak Hill Parkway crews with the space to build new bridges and walls that will extend the current US 290 freeway farther west.

With the eastbound US 290 frontage road closed at Joe Tanner Lane, travelers coming from the west attempting to access businesses and neighborhoods along both the eastbound and westbound US 290 frontage roads will detour to Monterey Oaks Boulevard.
  • Drivers heading east will follow the US 290 mainlanes traffic shift.
  • Drivers will return to the existing eastbound US 290 mainlanes just past Old Fredericksburg Road.
  • Drivers will then exit at Monterey Oaks Boulevard to make a U-turn to return to neighborhoods and businesses along the frontage roads between Monterey Oaks and Old Fredericksburg Road.
Construction Updates
Crews have started construction on 10 out of 26 bridges. By first constructing frontage roads outside of the current roadway footprint, crews working on an “outside in” approach can ensure US 290 traffic flows unimpeded.
East of William Cannon Drive, crews are constructing bridges for the new US 290 mainlanes. Pictured above, the team used three cranes simultaneously to place a cap cage onto support columns that will eventually hold the future elevated US 290 westbound mainlanes.
In the image above, excavators remove large amounts of soil and rock next to a retaining wall west of South View Road. Once this area is lowered to the desired depth, crews will begin building the future US 290 eastbound mainlanes.   
Between South View Road and Scenic Brook Drive along the eastbound US 290 frontage road, Oak Hill Parkway crews add final touches to new sound wall panels. These sound walls will help mitigate traffic noise for neighborhoods and businesses once construction is complete.
