Maryland Plans Four Miles of I-270 Paving

This $10 million project could start as early as this week, and will take until late fall to complete. All lanes of the Interstate between Muddy Branch Road and Middlebrook Road will be resurfaced, starting with the northbound side and switching to the southbound side at mid-summer.

The work is mostly overnight, but what I noticed last time there was a big paving project on I-270 is that the milling of the lanes, creating an uneven surface before the final paving, slowed down traffic somewhat. Use caution shifting lanes.

Work Schedule: Generally, there will be single lane closures along I-270 between 8 p.m. and 5 a.m. Sundays through Thursdays. Reopening of the northbound lanes can slide till 6 a.m., because the morning traffic southbound is dominant. Similarly, the start of a lane closure on the southbound side can be as early as 7 p.m., because the afternoon traffic is heaviest on the northbound side.

There may also be single lane closures in the collector-distributor lanes between Muddy Branch Road and the ramp to Route 124, weekdays between 9 a.m. and 3 p.m. and overnights, Sunday through Thursday, between 10 p.m. and 5 a.m.

I-270 is among the region's biggest and most heavily used highways. The average daily traffic in the vicinity of Muddy Branch Road and Middlebrook Road is 157,000 vehicles, the Maryland State Highway Administration said. Northbound averages 83,150 vehicles per day and southbound averages 74,000 a day.

Other Work: There also will be periodic lane closures overnight at the Route 124, Route 117 and Middlebrook interchanges. Watch for local detours during ramp closures, all of which will end by 5 o'clock each morning. These are the other elements involved in the work.

* Resurfacing the ramps at the Route 117 (W. Diamond Avenue), Route 124 (Montgomery Village Avenue/Quince Orchard Road) and Middlebrook Road interchange.
* Improving highway drainage.
* Upgrading sidewalks on Route 124 and Middlebrook Road at the I-270 interchange.
* Replacement of the concrete median and curb and gutter.
