Why RM 620 Near Hudson Bend Will Change Last

On the Mansfield Dam Bridge, RM 620 is down to fewer lanes in both directions. Some driveway crossings are restricted between Cloudy Ridge Road and Low Water Crossing Road. Crews are repairing the bridge's expansion joints, replacing the railings and resurfacing the road. TxDOT lists the job as active construction dated October 2026 and expects to finish in mid-2027.

That bridge work is the only construction on RM 620 near Hudson Bend before the 2030s. The six-lane widening that has been discussed for years is now on a regional schedule, and the stretches that meet Hudson Bend Road are the last ones on it. For the next several years, the road around the peninsula will change through repairs to what's already there.

What the Bridge Work Means Through Mid-2027

TxDOT describes the Mansfield Dam project as maintenance. Once it's done, the agency says, it will give drivers a smoother ride, improve safety and extend the life of the road and bridge. Nothing in the project adds lanes or reroutes traffic.

The City of Lakeway's October 16 newsletter says the closures will continue through the middle of next year and expects traffic delays during morning and afternoon commutes. Go Lake Travis passed along the same warning from the city on October 18. KVUE's coverage gives the same closure limits and the same mid-2027 finish.

The contract is fairly small. In state bid records, the RM 620 bridge maintenance is job 0683-02-086, bid June 2, 2026, and awarded to Gibson & Associates, Inc. for $3,335,184.39. That award also covers bridge maintenance on RM 2222 at Cat Creek, so the Mansfield Dam share is less than the full amount.

The Widening Begins at the Far End of the Corridor

On October 5, 2026, the Capital Area Metropolitan Planning Organization's Transportation Policy Board voted unanimously, 15 to 0, to approve its fall amendments to the 2027–2030 Transportation Improvement Program and the 2050 Regional Transportation Plan under Resolution 2026-10-7. The vote is recorded in the October 5 meeting minutes, which were included in the board's November 9 packet.

One of those amendments covers RM 620 from SH 71 to Dave Drive. It would widen that segment from four lanes to six, with construction set for fiscal year 2029 and an estimated cost of $151,200,878, according to the October packet. That segment is at the Bee Cave end of the corridor. As Community Impact reported in September, the full project runs from Hwy. 71 to RM 2222. The finished road would have six through lanes, raised medians, turn lanes at certain intersections and a shared-use path on each side.

CAMPO's long-range plan splits the corridor into three sections with different start years:

Both later segments end at Hudson Bend Road. Under this plan, the intersection where the peninsula meets RM 620 is the meeting point for the 2033 and 2035 phases, which makes it the last stretch scheduled for six lanes. CAMPO Community Outreach Manager Doise Miers told Community Impact that splitting construction into segments "is common and based on various factors."

Why the Hudson Bend End Has Waited Longest

The segment closest to Hudson Bend is also the one that has been fully designed the longest. TxDOT's project page for RM 620 from SH 71 to Hudson Bend Road shows the steps. The first open house was at the Lakeway Activity Center on October 10, 2018, the second at Bee Cave City Hall on June 26, 2019, and the public hearing at Lake Travis High School on February 20, 2020. The environmental finding came on August 3, 2020.

The page still lists the construction contract as "contingent on funding" and says TxDOT "is actively seeking funds to advance the project." TxDOT's description of the corridor explains why the delay matters. Along most of its length, the agency writes, RM 620 South is both a local road and a commuter highway, and in most cases it is "the sole access to subdivisions, businesses, and schools," as well as a main route to Lake Travis recreation.

The City of Lakeway has pushed for changes to the plan. On September 8, 2026, its City Council passed a resolution asking CAMPO to carry the six-lane project past Dave Drive, through Lakeway to Oak Grove Boulevard, and opposing a partial widening that could create a bottleneck. According to Community Impact, Mayor Thomas Kilgore said the plans for Hwy. 71 to Dave Drive could be read as ending the six lanes at Aria Drive, near the entrance to Lake Travis High School. The same report says Kilgore told the council that Lakeway has paid more than $3.2 million toward the project, with taxpayers paying nearly $1.1 million in interest on that debt. The Austin American-Statesman also reported the resolution, the city's request to coordinate with TxDOT and the $3.2 million contribution.

Lakeway's resolution was part of the city's comments in CAMPO's October packet. The board then approved the amendments, with the SH 71 to Dave Drive segment listed as written. CAMPO amends the program twice a year and adopts a new one every two years, so later cycles could still change how the segments are drawn.

The Lake Side of the Bridge This November

While the road schedule moves slowly, Lake Travis is high for this time of year. The Lower Colorado River Authority's river report put the lake at 677.12 feet above mean sea level on November 5, 2026. That is 94% full and 11.75 feet above its historical November average. LCRA lists 637 feet as the lowest usable level for the Mansfield Dam ramp, so at current levels the ramp has about 40 feet to spare.

The places just off the construction zone:

• Mansfield Dam Park, at 4370 Mansfield Dam Park Road. Travis County lists a four-lane boat ramp with a courtesy dock, open 24 hours a day, and asks visitors to check ramp status before they go.
• Good BBQ Company at Lake Travis Biergarten, 3519 B Ranch Rd 620 N. The barbecue trailer's second location has ordering at the window and picnic-table seating, according to Local Eats.
• Hurst Harbor Marina, at 16405 Clara Van Street, lists general hours of 9 a.m. to 5 p.m. daily.
• Chick-fil-A Lake Travis on RM 620 reopened in late October with an expanded drive-thru after almost three months of renovation, Go Lake Travis reported.

The holiday calendar on the Lakeway side of RM 620 starts in early December. Go Lake Travis lists Lakeway's Lights On! holiday kickoff on December 4 from 6 to 9 p.m. and a free Trail of Lights every night from December 4 through January 1 at Lakeway City Hall and the Activity Center. The City of Lakeway calendar also lists a Trail of Lights event at the City Hall Trail, 1102 Lohmans Crossing Road, on December 17 at 6 p.m. Before then, Hill Country Galleria holds its free Light Up the Plaza tree lighting on November 28 from 5 to 8 p.m. at 12700 Hill Country Blvd. in Bee Cave. On current plans, the Mansfield Dam Bridge lane closures will still be in place for all of it, with TxDOT's mid-2027 finish more than half a year away.

If you own along the RM 620 corridor and are thinking about the timing of a sale, or about how this road schedule fits your longer plans, Jeannie Garr would be glad to go through the dates with you. That includes what the bridge work means for showings over the coming months and what a widening still years away means for Hudson Bend. Schedule a consultation whenever it suits you.
