Steer clear of these work zones this weekend

Written by Jon Schmitz on .

There’s plenty of road work scheduled for the last weekend of September and first week of October.

And there’s the 35th annual Richard S. Caliguiri City of Pittsburgh Great Race, which will close streets and cause bus detours from Squirrel Hill to Downtown Pittsburgh from early morning to about 1 p.m. Sunday. Visit www. and for details.

And watch out for those spontaneous street demonstrations to celebrate the Pirates' 20th consecutive losing season.

Let's give Port Authority the floor before we get to the major highway and turnpike restrictions.

Both the Red Line and Blue Line will have detours this weekend due to rail maintenance. Port Authority will work on replacement of a bridge along the Library line this weekend, detouring Blue Line service from 8 p.m. Friday, Sept. 28 until end of day on Sunday, Sept. 30. This work involves a small bridge that carries the light rail line over a stream just south of the Monroe stop. During the work, Blue Line-Library service will terminate at Lytle, where riders may transfer to shuttle buses operating between Lytle and Library.

A second Blue Line weekend detour to continue bridge work will take place Oct.12-15.

For part of the day Saturday, rail grinding work continues on a section of the Red Line in Beechview. Inbound service will be impacted from approximately 5 a.m. to 12:30 p.m. Inbound Red Line service will detour via the Overbrook line (along the Blue Line’s routing) between Overbrook Junction/Willow and South Hills Junction. During this time, a local light rail shuttle will operate inbound from Overbrook Junction to Potomac, and bus shuttles will operate inbound to stops from Potomac to Station Square. Outbound Red Line service will remain on regular route.

All riders impacted by this weekend’s work should allow for extra time when traveling.

The inbound Squirrel Hill Tunnels will be down to one lane from 10 p.m. Friday to 10 a.m. Saturday for ongoing rehabilitation work. No work or restrictions will occur on Saturday night.

Inbound Route 28 will be closed at the Millvale exit, with traffic using the off- and on-ramps as a detour, from 8 p.m. Friday to 5 a.m. Monday. Police will assist with traffic control but beware — this caused pretty serious backups last weekend. Two more weekend closures are planned.

Overnight single-lane closures will continue on inbound Route 28 in Millvale next week, with one lane open after 8 p.m. Work concludes by 5 a.m. daily. The restrictions will continue on weeknights throughout October. Also, the ramp from Millvale to outbound Route 28 will close at 8 p.m. Mondays through Fridays until late October, reopening at 5 a.m. the next days. The detour is via the 40th Street Bridge, Butler Street and the Highland Park Bridge.

The Pennsylvania Turnpike will have two closures in Western Pennsylvania this weekend. The Monroeville-to-Irwin segment will close from 11:59 p.m. Saturday until 5 a.m. Sunday for placement of girders for a new Route 130 bridge over the turnpike. The detour is via Route 30, Turnpike 66 and Route 22. Route 130 traffic may face short stoppages Friday and Monday between Nike Site and Pleasant Valley roads. The pike will be blocked between Somerset and Bedford from 11:30 p.m. Saturday to 4 a.m. Sunday. The detour follows Routes 281, 219, 30 and 220. The closure is needed to set bridge beams for an overhead bridge at mile 132.

The ramp connecting the Liberty Bridge to northbound Interstate 579-Crosstown Boulevard will be closed from 8 p.m. Friday through 6 a.m. Monday for wall repairs.

Inspection of the Fort Duquesne Bridge will cause inbound lane closures from 6 a.m. to 10 a.m. Saturday.

Northbound Interstate 79 will be down to one lane near the Clever Road overpass in Kennedy, which is between Crafton and the Neville Island Bridge, from 4 a.m. to 3 p.m. Saturday for concrete repairs.

Route 65 will have alternating one-way traffic between Chestnut Street and Hazel Lane in Sewickley starting at 8 p.m. Friday and Saturday during paving, with the restrictions expected to cause significant delays. Work concludes by 6 a.m. Saturday and Sunday.

Banksville Road drivers face another weekend of delays as paving continues from 8 p.m. Friday through 4 p.m. Saturday. Traffic will be one lane in both directions from the Parkway West to Beverly and McFarland roads.

Repair of a landslide on Mosside Boulevard between Signal Hill Drive and Wall Avenue in North Versailles and Wall will reduce traffic to one narrow lane in both directions starting Monday and continuing through late November.

Milling and paving will begin Monday on Route 148-Walnut Street in McKeesport. Traffic will be restricted to one lane in both directions from Route 48 to the 15th Street Bridge at times from from 8 a.m. to 4 p.m. Mondays through Saturdays through mid-November.

Construction of a turning lane will cause lane closures at times on northbound McKnight Road at Browns Lane in Ross from 9 a.m. to 3 p.m. and 6 p.m. to 6 a.m. starting Monday and continuing through Oct. 31.

Howes Run Road in Fawn has reopened after 10 days of pipe repairs.
