Lawrence

• As early as Wednesday, crews along the Kansas Turnpike could begin steering drivers onto a new bridge crossing the Kansas River at the northern edge of Lawrence. First, traffic heading west on the turnpike will be directed onto the new bridge; a week later, traffic heading east also will be expected to be using the new bridge. Once traffic is on the bridge, crews will begin dismantling the two remaining bridges — each more than 50 years old — to prepare for removal by blasting, expected by the end of the year. A second new bridge would go in their place. Advises Rachel Bell, a turnpike spokeswoman: “During these changes and throughout the project, please obey all posted traffic signs and watch for construction personnel.”

• Crews from Southern Star Central Gas Pipeline are conducting inspection and, if necessary, repair work along an underground natural gas line along the west side of Monterey Way, south of Sixth Street. Late last week, work had closed a lane of traffic just south of Sixth. Work will be expected to continue through the week.

• Reconstruction of the intersection of North Second and Locust streets has closed both lanes of North Second heading north through the intersection, and one lane heading south. Northbound vehicles follow a detour including Elm, North Third, Locust and — crossing the Union Pacific Railroad tracks — Lyon streets. The restrictions are expected to last into late November or December.

• Drivers may face slow traffic periods as construction continues for a new U.S. Highway 59 between Lawrence and Ottawa.
