    • Vehicle access to the dog park via Randolph Ave. is closed for the duration of the bridge deck reconstruction and construction site cleanup. Users should access the dog park via Washington St. and may park on Spring St.
    • Pedestrian and bicycle access to the park will be available via the Randolph Ave. bike trail starting in December 2018.
      • There will be periodic trail closures through Spring 2019 during the construction site cleanup process.


Trail/sidewalk closures

Stage 4 of the Hwy 149 resurfacing project, which includes Dodd Rd, between Wentworth Ave. and Smith Ave, is currently scheduled for October and November. This work may extend into 2019 depending on weather. The delay of this stage is due to project-wide delays associated with utilities and other previously unknown underground issues inherent to reconstruction projects.

Project work items

There will be no construction activity the week of Dec. 25.

Construction viewing

If you are interested in watching construction activities take place near the site, please use the scenic overlook on the south side of the bridge. The view from this location is outstanding. It also is safer than using Randolph or St. Clair avenues. Those areas have been cordoned off for safety reasons.

River traffic impacts

Safety measures have been taken to ensure safe passage underneath the bridge during construction. Please be aware that there will be a barge and likely a tugboat out on the river. This should not impede passage of river traffic. Please use caution when proceeding through the area.

Construction noise

If you live near the High Bridge you may hear noise from jackhammering as crews work to remove the concrete bridge decking. The deck removal is scheduled to occur through mid-January 2018 as well as a brief three- to four-week period in June 2018, weather permitting.
