PROJECT SUMMARY

• Bridge Concrete Substructure Repairs
• (including work on Neville Island)
• Bridge Repainting – All Steel Members
• Drainage Repairs
• Bridge Barrier Repairs

Cost and Schedule:

• Estimated Construction Cost

$60M

• Anticipated Construction Duration

The let date for the project is 12-12-19. Physical construction is likely to begin with containment erection in March/April 2020. The project should be complete in the fall of 2022. 2021 – Fall 2022

Due to the site constraints of the project location and geometry, as well as most of the work

• ccurring on limited access ramps to the interstate, bicycle traffic cannot be maintained on

the highway shoulder. A bicycle detour route will be signed using the Sewickley Bridge

• Project includes 27-span structure over RR Tracks, Ohio River Backchannel, Ohio River Main Channel

and SR 0065 Ohio River Boulevard and the smaller 4-span structure to the north over Kilbuck Street

• Project Purpose: To maintain safe and reliable travel on this portion of I-79
• Project Need: Due to the physical deficiencies of the existing bridges causing Fair to Poor Condition

ratings.

Major Construction Activities:

• Bridge Expansion Dam Replacements
• Bridge Deck Repairs and Overlays
• Bridge Structure Steel Repairs
• Bridge Bearing Replacements

I-79 over the Ohio River

• During nighttime hours 8 p.m. to 6 a.m.: I-79 single lane and right-shoulder

closures in the northbound and southbound directions. I-79 remains open with lane restrictions, no detour.

• During weekday off-peak hours 9 a.m. to 3 p.m.: I-79 single lane and right-

shoulder closures in the northbound and southbound directions on the main arch span. Two (of three) I-79 lanes remain open in each direction, no detour.

• For bicycle traffic only, bicycle route normally on I-79 right shoulder will be

detoured via SR 0051, Sewickley Bridge, Broad Street, Beaver Street, SR 4028 Redgate Road.

• During weekends from 9 p.m. Friday to 5 a.m. Monday: I-79 complete

closure and detour northbound and southbound (only one direction closed at a time, four (4) northbound I-79 closures and four (4) southbound I-79 closures). Detour via Sewickley Bridge.

Ramp H, Exit 65 connecting Grand Avenue (Neville Island) with I-79 Southbound

• Long-term closure and detour of Ramp H via EXIT 66 Emsworth

Sewickley interchange. Closure is needed for long-term setup for parking and operating paint trucks and other equipment on right shoulders within the gore and ramp area. Ramp E, Exit 65 connecting Grand Avenue (Neville Island) with I-79 Northbound

• Long-term closure and detour of Ramp E Coraopolis Bridge

and EXIT 64 Coraopolis McKees Rocks interchange. Closure is needed for long-term setup for parking and operating paint trucks and other equipment on right shoulders within the gore and ramp area.

Grand Avenue on Neville Island

• Short-term single-lane closures for installation and removal of the

underdeck encapsulation overhead and work on concrete piers adjacent to the sidewalk.

• Contractor will stop construction activities and utilize flaggers to

allow safe passage of pedestrians passing through the workzone

• n the sidewalk. Resume work once pedestrians have safely

passed.

• For the eastbound lanes, contractor will close the right lane (left

lane) of Grand Avenue Eastbound and merge the right lane (left lane) into the left lane (right lane) and maintain one 11-foot lane

• f traffic on Grand Avenue Eastbound.
• Contractor will repeat the same process of left lane and right lane

closures on the westbound lanes on Grand Avenue.

Ramps A1 and A2, Exit 66, connecting SR 0065 with I-79 Southbound

• Long-term closure and detour of Ramps A1 and A2 via Kilbuck

Street, Deer Run Road and Ramp A3. Closure is needed due to limited vertical clearance, for installation and removal of

• verhead encapsulation and during painting of the four-span

structure over Deer Run Road. Ramps A1, A2 and A3 Exit 66, connecting SR 0065 and Deer Run Road with I-79 Southbound

• Long-term closure and detour of Ramp A via EXIT 68 Mount

Nebo Road interchange. Closure is needed due to construction vehicles blocking on-ramp to perform superstructure work requiring access from the I-79 bridge deck.
