The Wexford Interchange Project Is Also a Zoning Decision

Every few weeks this year, a new PennDOT advisory has landed for anyone watching Route 910 near Exit 73: a lane closed here, a ramp detoured there, beam placements scheduled for overnight hours. If you are touring homes along this corridor right now, you have probably already adjusted your expectations for the drive. What most tours will not tell you is that Marshall Township has already made a decision about what this stretch of Wexford looks like once the cones come down, and that decision has nothing to do with the ramps themselves.

Marshall Township supervisors amended the township's land-use rules to allow townhouses along Route 910 east of Mingo Road, a change aimed at reducing the number of individual driveways cutting onto the road. That is not a construction detail. It is a housing forecast, made in public meetings, tied directly to the same traffic math driving the interchange project.

Two Numbers That Don't Agree, and Why That's Useful

Pull up Wexford on two different portals and you will get two different stories. Zillow's home value index put the average Wexford home at $561,352 as of its May 31, 2026 update, up 2.7% year over year, with homes going to pending in about five days. Movoto's tracked median list price for Wexford in May 2026 sat closer to $575,000. Neither number is wrong. One measures estimated value across the existing housing stock, the other measures what sellers are actually asking that month. The gap between them is a reminder that any single number describing "Wexford" is doing some averaging across a corridor that is not uniform, and that matters more here than in most places, because part of that corridor is about to change on purpose.

What's Actually Happening at Exit 73 Right Now

The project itself is not a mystery. PennDOT's $46.5 million I-79/Route 910 Wexford Interchange project broke ground in August 2025 and is scheduled to finish in October 2027. Golden Triangle Construction is building a full offset single-point urban interchange, known as a SPUI, along with two new flyover bridges over I-79. The existing Route 910 bridge stays in place and gets rehabilitated rather than replaced, which is one reason the project didn't require taking new land.

As of this summer, the work is squarely in its bridge-building phase. Restrictions have run through Route 910/Wexford Bayne Road, Nicholson Road, and the ramps at Exit 73 on a rolling schedule: single-lane flagger control during the day, full overnight closures for beam placement, barrier relocations that shift week to week. PennDOT expects the new flyover ramps to open in early 2027, with the old ramps removed and final paving and striping following after that.

If you're touring a home in this corridor between now and late 2027, a few things matter more than they would for a typical showing:

• The commute you sample during a midday tour is not the commute you'll own. Peak-hour restrictions and evening ramp closures happen on a rolling basis, so ask your agent to check the current PennDOT advisory before you schedule a drive-by.
• Roads to watch by name: Route 910/Wexford Bayne Road between Nicholson Road and the interchange, and the I-79 ramps at Exit 73.
• PennDOT posts active restrictions and an email advisory list on its own project page, which is a better source than word of mouth if you're weighing how a specific closing date lines up with a specific construction phase.

None of this is unusual for a two-year infrastructure project. What makes it worth a longer look is what it triggered at the township level.

The Growth Number Behind the Project

Traffic engineers working on the project told Marshall Township supervisors that daily traffic on Route 910 at the interchange is projected to climb from about 19,000 vehicles in 2024 to roughly 34,500 by 2045, an increase of about 82 percent. Tom Madigan, chairman of the Marshall Township supervisors and a resident of the township since the early 1990s, put the interchange's role plainly: it functions as a feeder for the entirety of the North Hills, not just Marshall, carrying traffic bound for Pittsburgh as much as traffic staying local.

That projection is the reason the interchange is being rebuilt in the first place. It is also the reason the township didn't stop at the interchange when it updated its land-use rules.

The Zoning Change Nobody Toured For

Alongside the interchange project, Marshall Township supervisors folded a provision into an update of the township's land-use regulations that allows townhouses to be built along Route 910 east of Mingo Road. The stated goal was straightforward: reduce the number of driveways and curb cuts feeding directly onto the road from existing single-family lots, since each additional curb cut adds another conflict point to a road that is about to carry far more cars.

Franklin Park Borough Manager Zachary Filous described the pressure behind these changes in blunt terms.

"As this area's grown, it's had difficulty keeping up with the traffic. The proposed changes are to help mitigate that traffic backup in that area."

For a buyer, the practical read is this: the township isn't guessing that Route 910 will carry more traffic and more housing density over the next decade. It has already written that expectation into its zoning code. A home that sits along this stretch today is being sold into a corridor whose long-term character has already been partially decided by people who don't sell real estate for a living.

A Corridor That's Been Rezoned Before

This isn't the first time infrastructure has redrawn this specific stretch of road. When I-79 itself was originally built, Soergel Orchards, the longstanding farm market that sits near the interchange, lost 13 acres to eminent domain. When word of the current interchange project first circulated, a family member involved with the orchard, Voll, said the family was uneasy until the final design was set.

"We were rather nervous initially when we found out there would be another project and did not know what that could possibly mean. We were relieved the plan ended up being this way. It looks like a good plan to me."

The orchard wasn't affected this time, but the history is a useful marker for anyone evaluating property nearby. Big infrastructure decisions along this corridor have a track record of reshaping what sits next to them, sometimes through construction, sometimes through the zoning that follows it.

What This Means If You're Comparing Homes Near Route 910

If you're cross-shopping a home close to Exit 73 against one a mile or two off the corridor, the price difference on paper might look like the only variable. It isn't. A home closer to Route 910 is buying into a road that township planners already expect to carry 82 percent more traffic within two decades, and into a zoning framework that now permits denser housing on that same stretch. That can mean a different resale pool down the line, a different mix of housing types nearby than exists today, and a commute pattern that will look different once the SPUI opens in 2027 than it does today mid-construction.

None of that makes a Route 910-adjacent home a bad purchase. It makes it a different kind of purchase than a similarly priced home tucked into an established, already-built-out pocket of Wexford or Marshall Township. Before writing an offer on anything within a mile of the interchange, it's worth asking a few direct questions:

1. Is this parcel inside the stretch of Route 910 affected by the township's townhouse allowance, or outside it?
2. What construction phase is scheduled for this address's stretch of road between now and the October 2027 completion date?
3. Has the seller disclosed any recent changes to traffic patterns or access points affecting this specific property?

A local agent who has followed this project since the 2025 groundbreaking can answer these in minutes. A portal search can't answer any of them at all.

FAQ

When does the Wexford interchange project actually finish? PennDOT's proposed construction end date is October 2027, with new flyover ramps expected to open in early 2027 ahead of final paving and striping work.

Does the construction itself affect what homes near Route 910 are worth right now? The portals show Wexford's broader market holding steady through spring 2026, with Zillow's home value index up 2.7% year over year as of its May 31, 2026 update. Construction disruption tends to affect showing logistics and buyer patience more than it shows up as a standalone line item in pricing, but the zoning change tied to the project is a longer-term factor worth weighing separately from today's asking price.

Where can I check current lane closures before touring a home near the interchange? PennDOT maintains a running list of restrictions and advisories on its Wexford Interchange project page, updated as phases change.

Buying near an active infrastructure project means reading two timelines at once: the construction schedule and the zoning decisions riding along with it.
