While it seems like there’s endless construction along the Lehigh Valley’s highways, there is a strategy to all of it as the region’s transportation system tries to keep up with a growing population and the vehicles that come with it.

On Wednesday, the Lehigh Valley Transportation Study approved its major transportation investments for 2027-30 that includes $544 million for roads, bridges, mass transit and more.

“It really will help continue to improve the safety of our roadways, to reduce congestion, to support transit objectives as well as bike and pedestrian objectives,” said Becky Bradley, LVTS secretary and Lehigh Valley Planning Commission executive director.

The Transportation Improvement Program, which still needs a sign-off from the Federal Highway and Federal Transit administrations, is scheduled to go into effect Oct. 1.

This TIP is funded with federal, state and local money with guidance from PennDOT. About 80% of the funding comes from the federal government, with the remaining from local sources.

Of the funding, $234.1 million will go to bridge projects; $193.1 million for transit; $88.6 million for road projects; $20 million for multimodal transportation; $5.6 million for research; and $3 million for railroads.

The 2027-30 TIP includes more than 100 projects in the Valley. Some of the notable ones are:

• Continued construction on the Cementon Bridge between Whitehall Township and Northampton, $312,000.
